What are the Rimadyl side effects in Dogs?

Side Effects Of Rimadyl In Dogs

Rimadyl was released by Pfizer Pharmaceuticals in 1997 as a new “wonder drug” treatment for arthritis and joint problems in dogs. However, although Rimadyl is very effective in reducing inflammation and pain in affected dogs, it is now known to cause a number of potentially serious side effects in dogs, particularly the Labrador retriever breed of dog.

Before being prescribed Rimadyl, it is very important that a veterinarian runs blood tests on your dog to rule out any underlying health problems that could lead to a reaction with Rimadyl. If the results indicate that the dog might already have impaired liver function, use of Rimadyl should be ruled out immediately as it could lead to serious illness or death. Dogs with kidney disease or bleeding disorders should also not be prescribed Rimadyl.

What are the Rimadyl side effects in dogs?

The majority of dogs suffer no side effects from taking Rimadyl, but a small minority unfortunately DO experience serious side effects as a result of taking the drug, so it is very important that you are vigilant at all times and monitor your dog for signs or symptoms of a potentially life threatening reaction to Rimadyl. For reasons as yet unknown, Labrador retrievers are particularly at risk of serious side effects cause by Rimadyl and should not be prescribed Rimadyl.

Side effects of Rimadyl include:

Within a time frame of one to three hours the following symptoms can become visible in your dog with respect to how much Rimadyl was administered to your dog.

Symptoms to watch for are:

  • A loss of appetite and unwillingness to drink
  • Changes in urination patterns: sweet smelling urine, blood in the urine, and/or urinating far more than usual
  • Diarrhea
  • Vomiting
  • Vomit or stools containing blood
  • Changes in skin, including scabs, redness, itching
  • Change in normal temperament: lethargy, drowsiness, restlessness, aggressiveness, hyperactivity
  • Stumbling, staggering, partial or full paralysis
  • Seizures
  • Dizziness
  • Jaundice: yellow whites of the eyes, skin, and mucous membranes
  • Death
  • The side effects of Rimadyl are mostly attributable to liver, kidney, and gastrointestinal problems: in some dogs, Rimadyl causes ulceration and bleeding in the gut, damage to the kidney function, and liver failure due to Hepatotoxicity, all of which are potentially fatal.

    Side effects of Rimadyl can occur with hours of taking the drug, which is why pet owners must be extremely vigilant once Rimadyl has been administered to their dog. In other dogs, adverse symptoms do not appear until a few days have passed. Initially the dog might seem a little off colour—perhaps off its food and more lethargic than normal.

    What should I do if my dog appears to be suffering from Rimadyl side effects?

    If your dog has been given Rimadyl and you suspect it has had an adverse reaction to the drug, there are a number of steps you should take without delay. Firstly stop giving Rimadyl to your dog immediately, and then take the dog to your veterinarian clinic and tell them you suspect Rimadyl toxicity is the culprit. If the adverse effects of Rimadyl are caught quickly enough, the right course of treatment can be given and the dog should recover. However, it is a good idea to keep accurate records of your dog’s symptoms and treatment in the event that you need to make a claim against Pfizer for a refund of your veterinarian expenses.

      1. My 4 year old lab has been on rimadyl for 1 1/2 days for a sore and inflammation on top of a front paw. He has to pee every 10 minutes after taking 3 doses. I will be sleeping on the couch in the family room tonight.
        He had the same problem with medicine when he had to go under so the vets could deal with a bad ear infection. He peed for 2 days continuously every 10 – 15 minutes. I do not know if he was on rimadyl then. I thought it was the drug to put him under because it happened both times. I will find out tomorrow and get back to everyone!!! He will never take this drug again.
        Vets give out drugs without the disclosure that we get as humans! Something to get in the future.

      2. My heart is breaking with what I am reading in these comments. My 14 1/2 year old jindo/lab mix also suffered a seizure, on day five of taking Rimadyl which I reluctantly agreed to when our vet said at her age she had “earned the right” to some pain relief for arthritis. I have cared for this dog her whole life with fantastic raw and cooked human grade food, holistic supplements and she has even survived for a whole year after oral melanoma surgery, so rare. Only to have her felled by a hideous, carelessly prescribed evil drug. She is now staggering, walking into walls, getting stuck behind furniture and endlessly pacing. This is the 2nd day on milk thistle, Holy Basil, turmeric and Ashwaghanda to detox her liver and I am starting to see some slight improvement. But she is not the dog she was a week ago.

      3. I wish I had known:(
        My Cocker pulled a muscle in Feb & was in pain. I took him to the vet, she did a Lyme’s test, gave me the pills & said he would be fine. Two days later I called the vet due to paralysis of back legs, bloody bowls, and lethargy. She just said “bring him in & I will run tests”!! Wrong wrong wrong! I stopped the medication & treated him as though he had a stomach bug (no food, lots of water etc). It took him 2 weeks to begin moving & having bowel movements w/out blood! Three days ago he hurt himself jumping again so 1/2 the recommended dose one time before bed. Next morning diarrhea w/blood. Since then he has not been able to eat, & only passes blood. My vet never warned me…ever. I found all these horrible side effects and now everything makes sense. How is this product available, why do vets not warn pet owners & why if this has been known for so long-why do they still make it?!?!?

      4. Right now our seven year old Maltese-Shih Tzu mix is having what we believe to be Rimadyl side effects. A week or so ago she wasn’t eating or playing, and the vet thought she hurt her back so they prescribed Rimadyl. She got better at first, but started vomiting three days ago and now has bloody diarrhea. My mother took her off the Rimadyl immediately, but she didn’t improve. The vet said it was a side effect and prescribed Flagyl (metronidazole) to help her colitis. Still no improvement after two doses. Anyone had a similar experience? And anyone else had a pet prescribed antibiotics for Rimadyl side effects? I am so, so worried about our little girl… my husband and I don’t live with my parents, of course, but the sick dog and her Cavapoo brother are our babies anyway… they’re the family dogs, you know? The Cavapoo (who is quite a bit bigger than the Mal-Shi) has taken Rimadyl many times and it has worked wonderfully for him with no side effects. They, however, gave our little Zoe the same dose that he took, which I find confusing. Any thoughts would be greatly appreciated!

        1. My girl just died after a dose of this drug!
          She had an enlarged spleen and was due for surgery tomorrow ?
          I ask the vet if this was a good drug for it can cause bleeding and I was told it what she needed! And she died this morning I do t like this drug and I’m not into trusting vets just now I knew in my heart thus drug could be an issue so I asked again about it and was told it was better then tramodol? I’m so sad I miss her so!!

          1. Hi Alice,

            First of all our heartfelt condolences on the passing of your beloved dog to you and your family.

            Regarding your question(mark) pertaining to Tramadol compared to Rimadyl. Let me first tell you that you were absolutely right having serious doubts about Rimadyl. It’s a drug that can be very dangerous in certain situations – there are well over 300 real life stories on this website alone providing more than enough examples.

            The thing on Tramadol is that it is a synthetic opioid where Rimadyl is an NSAID. There is ample evidence that Tramadol as a pain reliever is far more effective on cats than it is on dogs. Therefore on it’s own it will do little to nothing to relieve arthritis pain but it often can enhance the effectiveness of other medication and therefore often is prescribed in combination with other drugs like Rimadyl.

            The problem is that both Rimadyl and Tramadol have the same (bad) side effects, in addition to this both drugs can only leave the dogs body through the liver and kidneys often causing serious weakening of both systems.

            I hope this short answer helped to make things a little bit more clear. We are planning to post a full article on the subject Rimadyl vs Tramadol in the coming weeks.

            You and your family are in our thoughs

            Warm regards

        2. Yes, although this happened a while back for you, the best thing you can give your dog are these things —alcohol free liquid Milk Thistle, 2,000MG (lots of places have it), and you daily one drop per every two lbs of your dog’s weight for 6 weeks. Put the Milk Thistle in food. The Milk Thistle is to heal the liver. Also get Manuka Doctor 24+ strength and give this on a regular stainless spoon. Some will like it and lick it off, and sometimes you have to put a tsp of it on the spoon and then rake it off onto his front teeth. It can heal ulcers, burns and all kinds of things. Also, be sure to ask for Sucralfate from your vet (demand it, no arguments). It is a tablet, but must be dissolved in a syringe in pure water so you can drizzle it into your dog’s mouth twice a day about 30 minutes before feeding. This drug is very mild and helpful, and is known to not only soothe the digestive system, but cure ulcers as well. I have done all of this after my dog vomited blood and had bloody diarrhea from Rimadyl, and it did work to stop the bleeding and upset stomach. Metrodionazole will NOT help yoir dog’s reaction to Rimadyl. That is only for things like getting rid of candida in the gut. I wonder sometimes about these things I hear. Having had dogs since 1984, we have learned a LOT, and we have a sensational vet who explains everything.

      5. I gave Rimadyl to my 14 year old shitzu who had his bloodwork and X-rays come back completely normal a few hours prior to giving hine the pill. I only administered one pill and within an hour he was hacking as if he was trying to cough something up. I called the emergency vet who said he was probably just relaxed from the pill and coughing was not a reaction to Rimadyl. Within 4 hours he was struggling to breath and I rushed him to the emergency vet at 4 am in the morning. They immediately put him on oxygen and began administering antibiotics. They performed another X-ray showing fluid now on the lungs. He was given lasix and at 8 am I took him to the internal specialist. They performed tests and melts him on oxygen and fluids, antibiotics, lasix, etc but within a day he was gone. He was taken to A&M where a necropsy was done and his cause of death was due to a sudden onset of pneumonia. This was an old dog, but never had this issue prior to Rimadyl and for it to be within an hour of giving him the dose to go downhill this quick the vet believes there is a possible link to the pill. Please beware before giving to an older dog… I have used this same pill for another 10 year old dog who went lame out of nowhere and it made the world of difference with him with no adverse reaction. Unfortunately that was not the case for our Gizmo.

      6. Dear all, it came too late for me as well, after taking 25mg of Rimadyl for four days, for limping after a walk, my 11 yr old cocker spaniel’s appetite decreased massively and she turned into a moody and depressed dog. Although she has no violent vomit nor bloody stools, she seemed to have completely lost her appetite, eating only 1/3 of her regular portion.

        Having stopped Rimadyl four days ago, she still hasn’t recovered and still is a depressive state. Anyone can advise on how long this will last? Her urea is 4 times higher than prior to the drug, but all other things are normal and urinalysis did not show any abnormalities as well. God, i just want her to be back to her happy, greedy self.. anyone can tell me how long does it take for the effects of Rimadyl to wear off?

        1. Please see my recommendations above another comment. It can work. They side effects don’t usually wear off. The liver, and the intestinal tract need to be treated. You can do this. Best wishes.

      7. A dear friend died and I now have her small dog, who is on Rimadyl. I will no longer give it to her, since it is for joints and arthritis pain and inflammation. I had been limping markedly for 2 years , was seen by 3 orthopedic surgeons and scheduled for a total hip replacement. One physician told me, when I asked about alternatives, that about 50% of people respond to Glucosamine and Chondroitin. Within 5 weeks I was speed walking and canceled the surgery. That was 2 years ago. I will probably take it indefinitely. I gave it to our dog who could no longer climb steps and he recovered. I will put this baby on that plan. No fear of overdosing…they are food products. I could not afford the special doggy brand so I got mine at the Dollar store or Walmart and ground up both in a mix to store in a jar. Then I gave 1 tsp daily to the dog. He was a G. Shepherd. Blessings…

      8. I think it has killed my chocolate lab he is dying now in the vets office i never read the side effects or knew about them he had redness of his skin and itching but that was it and then all of a sudden he started to coughing and cough up mucus vet said he had bronchitis and he started stumbling and falling down vet said he is loosing blood somewhere in his body and won’t last long

      9. I have found that the chewable tablet had more side effects. I spoke to my pharmacy they said that the binders could be causing the problem. If you talk to your vet and see they think the pill form.

      10. My dog is an 18lbs chihuahua/pug mix. I took him to the emergency vet on Monday because of what I thought was an illness. They took xrays and said he has inflamation and gave him Rimadyl for 7 days. 75mg that they prequartered. No bloodwork was done… now he is super lathargic and his limbs are trembling.

      11. My 6 year old Springer Spaniel was given Rimadyl today by the vet as he had a limp. She thought he had dysplasia of his knee joint on his front leg. He’s hardly moved today and keeps staring at me as if to say ‘what’s going on’.
        A couple of years ago I lost a previously healthy terrier with chronic pancreatitis after a course of Rimadyl, I didn’t put 2 and 2 together at that time. I will not give my dog any more Rimadyl, I’d rather he had a limp rather than the poorly dog I have in front of me now. He won’t drink either, I’m worried he won’t get well now. A sleepless night for me ahead. If you can’t trust your vet, where do you turn when your animal needs help? I was only told he may be a bit sleepy as a result of this medication! Really don’t know what to do, other that not to administer any more Rimadyl.

      12. Earlier this week, my dog had massive bleeding and died. Given this drug due to eye irritation. She was otherwise healthy. Horrifying.

      13. I’ve taken my dog (field spaniel) Sammy off of Rimadyl just this past week on Sun. He’d been on it for about 1-2 yrs. I feel all the strange things that have happened to him since have been due to the Rimadyl, and I didn’t put them together. Here is a list of symptoms he has developed since placed on the drug (Started on it Jan 2015);
        -constant panting even at rest (I thought he was becoming activity intolerant-he was 13yo)
        -activity intolerance (just going for short walks)
        – polydipsia (extreme thirst)
        -polyphagia (extreme hunger)
        -lethargy
        -polyuria
        -3 episodes of severe dizziness, vomiting, diarrhea, anorexia (he was diagnosed with vestibular disorder. Now I think not. I think it was the Rimadyl)
        -Hair loss and itching. (I was told it was related to the anesthesia he’d had for skin growth removal.) I think it was the Rimadyl all along.
        -Recently, since last Sat.-severe diarrhea, frank blood in stool.
        -Thankfully his liver and kidney function have always been good.

        I didn’t call my vet, I took him off the Rimadyl, treated the symptoms, and prayed to God to restore my dog’s health. His diarrhea stopped on -Wed.

        I will be calling a number I found to report Rimadyl adverse reactions to. -1-800-366-5288 From the Rimadyl manufacturer’s website.

        1. Wow, this sounds just like my dog! He’s been on Rimadyl now for about 1 1/2 years. I’m taking him off tomorrow! Thank you for leaving your comments!

        2. Wow, this sounds just like my dog! He’s been on Rimadyl now for about 1 1/2 years. I’m taking him off tomorrow! Thank you for leaving your comments!
          Have you noticed a difference now since he’s been off the drug?

      14. I took my 10 year old boxer to the vet because he started limping after a run. They gave him a liver test, which came back with slight elevations. The vet gave him Vetprofen (generic Rimadyl) and tramadol. I was told they could be taken together, and that the Vetprofen 100mg, could be taken every 12 hours (1/2 pill).

        I work a lot, so I was not able to spend time watching how he was doing on the medication. I had him sleeping downstairs for a week to rest his leg. One morning I saw him drooling profusely, which was not normal, but I did not make any connection. Two days later I noticed that he has having trouble standing on his back legs, or really getting up off the floor. He seemed oriented though, just week in his hind legs. That day he had a seizure in the car. After seizure he was panting, agitated and drooling profusely again. He had probably had seizures all week.

        I took him straight to the ER, and they kept him over night. I got a call the next morning that he had deteriorated that night and they were unable to tell me what was happening other than it appeared neurologic.

        When they brought him into the room he was in a harness cause he couldn’t walk. His eyes were drooped, he was hacking and his nose was shooting out green boogers. He looked half dead. He tried to lick me but couldn’t get his tongue out of his mouth. Honestly, he looked miserable, like he had had a stroke overnight.

        I made the decision to put him down. It was devastating. I hope I didn’t miss an opportunity for him to recover by waiting it out, but he just looked half-dead. Ultimately, I feel like I poisoned him to death, and have a tremendous amount of guilt.

      15. Boomer (Black Lab) slipped on the wood floor and hurt his leg.
        He had just had his yearly exam and heart, liver, everything was fine.
        Doc prescribed Rimadyl for him. I got him home and gave him his Rimadyl and about 10 minutes later he started panting very hard. His heart was racing so fast it was shaking his whole body.
        Scared to death, I called the vet and was told he was panting because he was n pain and that I should double the dosage, which I did.
        Within an hour he could no longer walk. At 85 pounds I had to drag him outside on a blanket for him to pee. He was the type of dog that would allow his bladder to burst before he went to the bathroom inside.
        I Called the vet again and insisted they see him.
        I was informed that his heart was damaged and failing and that he needed immediate heart surgery or put on a machine at an acute care vet hospital.
        At around $10,000 they could maybe prolong his life 48 – 72 hours but no longer than that.
        I decided to see how Boomer was in the morning and intended to take him to doggy hospital.
        That evening he walked back the hallway and laid his head on my knees and looked up at me. I could see the pain i his eyes.
        He laid down at my feet, howled 2x and died.
        His heart and my heart burst.
        A friend buried Boomer next to the flower bed in the front yard.
        Can I prove Rimadyl is hat killed Boomer? No. I can’t prove it but I KNOW it is what did it.
        My family prefers I never get another dog.
        No one wants to see me go through what I did when Boomer died.
        PLEASE do not allow a vet to give a lab Rimadyl.
        Since then I have read many many cases of this happening.
        This happened in 2005 and I still miss him every single day.

      16. Like so many others, my almost 13 year old lab mix, who weighs about 110 pounds, had an elbow issue after running around. My vet prescribed Rimadyl. I gave it only as needed, which amounted to once a week, or every few days, no problems. Recently, after he started limping again, I gave him rimadyl for about 3 days in a row, 100 mg, once a day, which was less that the 200 mg prescribed dosage. Yesterday, his limp didn’t seem to be improving, so I gave him 2 for the first time. Several hours later, he was lethargic, weak in his BACK legs, and panting like crazy. Appetite, great, as usual. However, he did not seem to be peeing as much as normal, but his poop looked good. As the day went on, he continued to seem unwell. Finally, I got to thinking it might be the rimadyl. I didn’t give him any this morning, and he is much improved today. I am so hoping I didn’t cause any permanent damage. My at home vet, and friend, doesn’t believe it could be the rimadyl, but I respectfully disagreed. He’s coming over Friday and we’re doing a blood panel. NO MORE RIMADYL, either way!

      17. My Boston Terrier will be 9 years old in November 2017. was prescribed Rimadyl 75 mg 1/2 tablet every 12 hours for neck & shoulder trauma injury due to a car accident we had. He has been on Rimadyl since 2013 on & off ( during cold winter weather & when he chases after rabbits ).
        Recently he started to pass drops of blood after urinating. Lab results revealed liver & kidney are in normal range . He has had a few other symptoms associated with side effects from Rimadyl, such as unwillingness to drink water, and eat, slight aggressive, and has slightly stumbled trying to get on to the bed.
        Ultrasound revealed enlarged Prostate. In the last year he has had the drops of blood after urinating happen 4 times . He was given a generic form of Baytrail for possible urinary tract infection. Each time He had the drops of blood after urinating I stopped the Rimadyl and the bleeding stopped , when I began Rimadyl the drops of blood returned . Is this a coincidence , or is this a side effect to Rimadyl . My Veterinarian that I have used for over 30 years, states this is due to an enlarged prostate, and a neuter surgery is necessary. I know when Rimadyl is not given My Boston Terrier is in chronic pain to the point he can not walk , and breathing is very hard for him, due to the excessive panting dogs do when in extreme pain.
        Can Rimadyl cause side effects that occur after taken this drug for several years ,or is it something that ONLY happens , within the first few days of initial use.

      18. Our 11 yr old Lab was DX with hip dysplasia 1 yr ago. Given Tramadol, Rimadyl and Gabapentin. Been good for the last year till yesterday and started with blood in stool. We took him to 2 specialists (neuro and ortho) last year, the ortho put him on Rimadyl and our vet took over and continued with RX but NO ONE out all 3 of these “professionals” said anything about monitoring blood or Rimadyl side affects. Ever. If anything, Vet was put out when we asked for RX to be distributed by Allivet since cost was 50% less than vet, who was charging $157/mo. So it’s now no wonder these miserable veterinarians DON’T tell you about the drug side affects – they have a HUGE financial interest in prescribing it. No different than MDs out there who have stock in the pharmaceutical companies so they prescribe meds that are harmful to humans.

      19. We had our Lab that is 10 on it or pain and with in a week he had a reaction and spend several days in the Hospital. his liver enzymes went off the chart. Can close to losing him. Becareful giving this drug to your dog

      20. My dog starts to rimadyl for limping 3 days ago . He is 70 lb and 2 and a half years old. I gave him 50 mg for first day. He was just sleepy . Second day i gave to him 50 mg again . One hour later he starts to look like he is sad or something like that. Sleepy but not a real sleep , moving like a drunk , licking his paws and sheets almost till morning. I did not sleep and monitored him and start to search and find this site… read all comments and did not give the pill today . He is normal now . I could not think what would be happen end of the week . He is still limping with lots of energy and smiles which we are prefer this. Thanx for every ones warnings .

      21. We have a 181lb Saint Bernard – he has an autoimmune disease of his muscles (in remission thankfully), and also bilateral hip dysplasia. He was put on Rimadyl about 3 weeks ago, and he has been SO INCREDIBLY itchy, and has developed little red bumps/sores sporadically over his body (legs, neck, back). He has NEVER had a flea on him, ever. I kept thinking some kind of food allergy or environmental allergy, but the only thing that has changed is starting the Rimadyl. We’ve been to our vet twice for the itching since the start of the Rimadyl and not once have they suggested or even mentioned this being due to the Rimadyl. Then my husband put two and two together today….which led me here. He will not get one more pill! Thank you everyone for adding your stories, as it helps all of us be informed.

      22. My 1 year old pit mix just had her spay Surgery this past week, they gave me tramadol and Carprofen, i didn’t start her Carprofen until the second day after her surgery and by night her neck was swollen, rash like, and extremely dry. It also seems like there was some sort of fluid building up. I didn’t want to continue the Carprofen; the vet that did her surgery is not open until Monday, I didn’t know what else it could have been since she has been with me since her surgery practical all day everyday. The swelling lessened through out the day today. But i haven’t seen any information about swelling in the neck caused from this drug. I was very worried this morning, waking up to my pup who usually has very little extra skin and folds now with a whole new neck lump! Not sure how to take care of it until i can get her into the Vet Monday. Any ideas?

      23. Rimadyl/ Carprofen was given to my Golden retriever for her spay surgery and for pain after the surgery– she was sick the day following with vomiting and diarrhea– called the vet –said to not give the carprofen–may be allergic– took her back to vet 2 days post op for meds to calm her GI tract –she seemed to be on the mend until she dropped dead on day 5 post op–autopsy showed blood pooled in her spleen and did not get out to other organs– her heart stopped and she died! He said she developed IMHA with DIC—I know that drug started it all into play—SO MAD–How do you trust these vets?? Her gums were pale and there was no saving her–we were just out to potty and she was wagging her tail walking with me–she stumbled and was down and dead–I will never forget the ordeal. I wish I had not taken her in to be spayed– Vets need to keep educated on these damn drugs and problems they can cause.

        1. Hi Mary,

          We are truly sorry to hear about your loss, please accept our condolences on the passing of your dog.

          There are several (research) studies published on the topic of IMHA and DIC and all speak against administering drugs that may cause bleeding such as aspirin or NSAIDs.

          Losing your dog is a deeply sad event, no matter what caused it.

          You and your family are in our thoughts.

          Warmest regards

      24. Our Chihuahua just died from Rimadyl! She was 16 and the vet gave it to us to give to her for her arthritis. Before that they did blood work on her and all of her bloodwork was excellent, no heart damage, no kidney or liver damage, they could not believe the numbers and how healthy she was for an old dog. We gave it to her for 1 1/2 weeks and last Wed night in the middle of the night she had a really bad seizure, bit her tongue and blood aspirated into her lungs. She came through the seizure but was laboring in her breathing because of the fluid in her lungs. Took her down to the vet they checked her heart which was good, did x-rays and all looked good, so the only thing they could determine is that during the seizure she got a lesion in her brain (stroke) which damanged the part of knowing where she was, totally lost. She had never had seizures before and was never on any medication in her entire life! That night was the first night also that they had us give her Trazadone for her anxiety.

        We are so lost without our baby girl, we loved her so much. If I would have known that this was one of the side effects of Rimadyl we would have never given this to her. Of course the vets to not give you any information on it. When a human gets a prescription at the pharmacy we are given all kinds of info on it, including side effects and our decision if we want to take it. But in this case I guess we were suppose to trust the Vet. A piece of us died with our baby and I blame myself for giving her this drug without researching it. But we were told oh it is safe and will help her.

        I would advise anyone with an older dog not to give them this drug for sure, even a younger dog.

        1. Hi Linda,

          I am sorry to hear of your dog’s passing. I understand that this will leave you with varying emotions. You will have good days and bad days in the coming months or perhaps even years but please try not to blame yourself for this.

          The thing is when we take our dogs to a vet we simply have to place our trust into their knowledge and experience because that’s the only thing we can do as a responsible dog owner.

          What happened to you and your little dog is a terrible thing and we fully understand that nothing but time itself will be able to change your feeling of pain and loss.

          Our deepest sympathies go out to you and your family at this time of loss.

          Our warmest regards

      25. Our dog Socks was a Lab/Pit Bull mix eleven years old with never a sick day in his life.. He was having just a small bit of arthritis (the Vet told us) and without knowing one was not supposed to give it to him I gave him one Tylenol. He was 77 pounds and in excellent health. Socks seemed a bit “spaced out” and I was afraid it was the single Tylenol. I immediately took him to the Vet again and was told, yes, arthritis and I was given 60 -75mg Rimadyl chewable and 60 Gabapentin capsules. I was told to give him one each of the pills twice a day. As soon as I began the pills Socks began to be very quiet and laid down a lot. We went on a walk and he seemed OK but when we came back he would lay down immediately. I didn’t like the situation so I only gave him one Gabapentin before I stopped those completely but continued the Rimadyl. The Vet gave me no cautions about either medications usage. The Tech said Socks would “act like a Puppy again soon”

        Socks continued to decline with panting when there was no reason to pant, refusing food but still drinking some water . For specially liked treats he would eat a small piece of chicken and then refuse any more. On short walks he would urinate often. He started to have very small black, tar like stools consisting of black outer layer and more normal color inside. He was his normal mentally bright self except for the tiredness and a desire to be by himself in the back yard all night which he never has done before as we have a dog door installed.

        After 8 days of the two per day Rimadyl I stopped it as he was getting worse with now no eating and not as much drinking. I assumed he would get better, but he continued to fail.

        His now much shorter walks showed that while his front legs were strong, his entire rear end and legs sort of wriggled back and forth from side to side and his back legs were close together. and lacked energy. We went back to the Vet when he couldn’t get up because his back legs became suddenly paralyzed. (One week after stopping Rimadyl) We were referred to an emergency Vet hospital where it was determined that he was bleeding into his spine causing paralysis. His blood platelet count was VERY low and the Vet asked if we had any Mouse Poison around. We have a small amount in a false ceiling for mice but it is not accessible to a dog so that was not it.

        Vet opinions ranged all the way from Rimadyl to silly things like unknown cancer which no one had found in a sweet active, normal dog but there was no “proof” of anything. After about $600 in vet expenses, it was suggested that they could do a CT scan to find the bleeding site ($1400) and that might give them more information. They were good in reminding me of the many dogs Rimadyl has helped, but never gave me a warning about the damage it could do. I found this out on the Internet and sites like this. Thank you.

        We had to euthanize socks yesterday a week after I stopped the Rimadyl and about two weeks after he started on it. . (Yesterday was also my wife’s Birthday) and we are so sad with a dear 11 year friend rather than a pet missing, who was always there with a wagging tail and uncaring love. I hope that anyone reading this is so VERY careful with this VERY dangerous drug. I would never advise anyone to use it on any animal of concern.

        My religion teaches me that all life will be fully resurrected so I look forward to seeing Socks again in a place where I can throw and he can chase real balls and run and play in real fields again always. But for now I miss him greatly.

      26. i TOOK MY DOG TO THE VET SHE WAS HAVING PROBLEMS WITH HER BACK LEGS. THE VET GAVE HER THIS TERRIBLE INJECTION NOT 10 MINUTES LATER MY BEAUTIFUL BABY WAS GONE!!!!!

      27. My Morkie was put on rimadyl for Luxating Patella 3 weeks ago against my better judgement… with in 24 hrs he was chewing his back like he had fleas(which he does not) Foolishly I waited to look up side effects of this drug and after 10 days I did. As soon as I saw that it was a side effect I immediately took him off it. He now has a bald spot the size of a 50 cent piece. He has been off it for several days and he is still itchy. He has never had any itchy or skin issues. Hopefully he will begin to heal now. I am so sick about it.

      28. Thank God that I read all these terribly sad stories, that made me cry! My dear, little, 10 yr. old dog (adopted in Dec., after my darling 16 yr. old, big dog passed away, sadly), was prescribed Rimadyl because she fell over a couple of times. The vet told me that her back knee came out of socket, so I asked if I could give her Glucosamine, given that my big dog was taking 1,000 mg. daily (which stopped shaking in her back legs). I was told that I could do so and in a couple of days she was back to normal, with my not letting her jump up/down steps, etc. Therefore, I wondered about starting the Rimadyl — didn’t want to make too many changes all at once — so I halved the 25 mg. pill and gave it (after food) midday, given she was getting the Glucosamine in the morn. and eve., after her meals . However, on our walk (tonight) she seemed slower than usual and panted quite a bit! Consequently, I thought I’d do some research on what Rimadyl actually does (vet told me it’s for inflammation), and I’m very grateful that I found this info.! I shan’t be giving my dog anymore Rimadyl! She was doing well without it, and so, God willing, she’ll be her usual happy self again, in the morn. I’m so sorry that people lost their beautiful dogs, because they were given Rilmadyl, it seems. It’s absolutely heartbreaking! Thank-you very much for sharing your tragic stories, which could have saved my little dog from the same suffering.

      29. My dog took Rimadyl for 2 1/2 weeks before noticing the negative effects. First issue was paw itching. She never chews on her paws and was doing it incessantly one evening. I thought maybe she stepped in something on our long walk. The next day she started shaking her head (like an ear infection) and seemed a bit off on our walk. Not her normally smiling self. I awoke to vomit all through my home. This dog never throws up in her 7.5 years in our home. I decided to stop the medication that morning. By evening I came home and my dogs ear flaps were swollen to about 1/2 inch thick to include her muzzle and the house again was filled with vomit. I also found two blankets with blood circles on them which I assume came from her anal area. I took her to the vet and luckily after 9 days she appears to be herself. While she is limping I’m glad she is alive. My vet did not suggest I report this as an adverse event to Zoetis which leads me to believe most people are not reporting these issues so the incident rate for side effects is not properly being factored in. So a 1% incident rate is probably more a 10% likliehoold of a negative outcome.

        1. Hi Alyson,

          Glad to hear your dog is alright again, you absolutely saved her life.

          Your absolutely right in assuming only a fraction of the problems is being reported. The Rimadyl problem is going on for years now and the problem cases keep piling up.

          I think it’s unbelievable that products like that are still prescribed by veterinarians.

          Earlier today I read a post on a vet’s website stating, quote: “Treatment for arthritis is relatively easy, and can make a dramatic difference to your pet, allowing them to be more active”.

          They also mentioned “There are many over-the-counter supplements or prescription medications to assist your pet’s joint health and enable it to move more freely with reduced or minimal pain.”

          After reading that post I left a comment asking warning about the risks connected to many of these types of medication and my comment was removed from their site within five minutes after posting it. The same happened to the second comment I posted, asking for the reason of such a tight level of censorship.

          Anyway, thank you for sharing your story with us.

          Warm regards

      30. I came across this post after picking our ten month old golden up from the vet. He had been prescribed rimadyl after a surgery on Friday (June 1 st) Saturday, he seemed fine, but Sunday I was welcomed to a mess of diarrhea and bile on our laundry room floor. I cleaned him up, stopped the rimadyl and began on the white rice and chicken regime. He had less diarrhea on Monday, and was up and around. When I returned home from a running errands on Tuesday, he stood outside and lost a large amount of blood from his rectum. I cleaned him up and called the vet. He now has him on metronidazole twice a day for the diarrhea. I am wondering if the rimadyl could still be causing this gastrointestinal bleeding as it is very concerning. Thanks

        1. Same here. We have a year old lab….Just had her spayed Thursday, June 7, 2018. Started Rimadyl on Friday the 8th. Diarrhea started Saturday, the 9th. Discontinued on Sunday the 10th……Monday was a fair day for her, no vomiting, however minor diarrhea. Today, the 12th, four bouts of diarrhea. Took he to Vet today, she stated, she might had reaction to Rimadyl. Three or four pills did this to my pup…..

          Started her yesterday on Scrambled eggs…..very hungry. White Rice tonight. Immediately had two bouts of DIARRHEA. STILL VERY ACTIVE AND PLAYFUL…….

      31. We just recently lost our beloved baby girl dachshund of 9 1/2 years to this drug Rimadyl. We had no idea of the side effects of this drug our vet prescribed to us. We took her in with a limp and were given these pills for her. She started them on a Wednesday night we stopped them Saturday and it was a cascading series of devastating events afterwards. She stopped eating, drinking, and walking. She ran a high temperature. We took her to another vet and they started treating her but it was too late, her liver shut down. In the end her ears were scabbed, and her little belly was turning yellow. My kids and I love her so much but had to say good bye. This has been an absolutely horrible few weeks. We did everything we could to try to save her. I feel horrible knowing that I gave her the medication that ultimately cost her her life and I’m so angry that I didn’t research this medication. My kids and I are devastated over the loss of our tiny companion. I assure you she was only given 3 days of Rimadyl, this is how fast this medication can take your dogs life. Just don’t give it.

        1. We’re very sorry to hear about your loss and yes, it is an extremely dangerous drug.

          I know it is almost impossible under the given circumstances, but please try not to blame yourself for what happened, you did your best to help her and by sharing this with the readers of this website, which is not an easy thing to do, believe me I know, you are informing other dogowners about the dangers of NSAIDs like rimadyl.

          Our condolences go out to you and your family.

          Thank you again for sharing.

      32. Our 3 year old Scotty was put on Rimadyl for atorn tor web. Took drug for two days. Thursday AM to Friday PM By Friday evening she was weaving falling down shaking her head side to side. Took her the Vet Sat. AM. Diagnoses was some sort of Nerological issue. Vet prescribed a steroid. But first had to wait for Rimadyl to wash out. By Sat. PM she needed to be carried everywhere. Went to Vet on Monday, new diagnoses, “CA” decease. Devastated Actually saw some improvement before Vet visit. By Tuesday Am she was almost herself again. Drug had washed out of her system. Vet did not mention side effects. This drug may be good for some dogs, but beware if you see any radical change stop the drug right away.

      33. Our 6 month old lab was given rimadyl after her spay surgery. She started to become very lethargic, lost her appetite, had noticeable limb and muscle weakness, and eventually had three seizures in one day. The vet immediately took her off rimadyl and switched her to prednisone and we begin to see immediate improvements. Apparently Labradors should never be prescribed rimadyl. Something I will certainly remember for the future, as we very nearly lost our sweet girl.

        1. Hi there,

          First of all, let me say we’re very happy you were able to get your Lab out of immediate danger.

          One of the side effects of Rimadyl is chemically induced liver damage (Hepatotoxicity) and unfortunately, history has proven Labrador Retrievers are more sensitive to attract this type of liver damage than other dog breeds.

          The thing is, up until now, the exact mechanism of Hepatotoxicity is not completely understood, there is some speculation though, that specific proteins in liver cells (hepatocellular proteins) will react to Rimadyl (and other NSAIDs) causing damage to the liver (Hepatotoxicity).

          Hope everything will turn out well for your little Labbie, by the way, Labs are one of my favourite dog breeds. Check-out Facebook for this group Labradors SemperFi

      34. My Bouvier 7 year old has been on Rimadyl for 2 years ,and the only reason she is off was because she developed a skin condition with scabbing, itching ,ulcers. The vet decided she needed to be on Prednisone and amoxicillin for her skin. I had to research on my own whether pred would react with the Rimadyl , as I am pretty cautious about mixing drugs. When I called my vet’s office to inquire about the drug combo they said wait 48 hrs with no Rimadyl then start pred. After everything I have read here she will never take that drug again. It was given for arthritis pain and seemed to help at first but she has had off and on skin itching that vet has said we’re allergy related. Allergy to Rimadyl is what I think. I am so grateful it was not fatal.

        1. Hi Madylon,

          One can never be too cautious, so well done!

          As a rule NSAIDs like Rimadyl should never be given with steroids, for example, prednisone, dexamethasone, triamcinolone.

          The changes in her skin condition you described (scabs, redness, itching) all belong to the list of most common Rimadyl-related side effects.

          By the way, Bouvier des Flandres, a real family dog, smart, loyal and protective, yet very friendly by nature.

          Thank you for sharing your story with us and warm regards

      35. My Boston had a tumor removed three weeks ago and was given this for pain. She had no side effects that I noticed. I gave it to her for maybe 5 days post-surgery. I can say she was not as spunky and her appetite was not great. She cut her paw and had to have stitches Tuesday. Today, Thursday, after 3 doses she is throwing up with blood in her stool. I stopped the drug, and no food. She is drinking water. I am scared I will lose her after reading all of this. I am monitoring her closely. I was never, ever told these side effects. I am angry, scared, and upset. She is 10 and I am so scared I will lose her. Should I take her for bloodwork tomorrow? This medication is evil, and I will never give it to her again!

        1. You stopped the treatment, that is great.
          The main thing is to take her to a veterinarian and keep monitoring her closely.
          I hope everything will turn out OK for you and your little Boston buddy.

          Keep us posted.
