Is Rimadyl Safe for Dogs?

The controversial use of Rimadyl in dogs has caused many dog owners to ask “Can Rimadyl kill a dog?” Rimadyl is a prescription medication used to treat osteoarthritis and the pain associated with it.

Rimadyl Killed My Dog

Since it was first introduced to the market, Rimadyl has been reported in hundreds of cases to cause adverse side effects and even death in dogs.

“At first, everything seemed fine. After a few weeks of taking Rimadyl, my dog didn’t seem to feel as much pain anymore with his arthritic joints. But then I noticed that he was walking strangely and he looked kind of drugged up. I took him back to the vet for a checkup and she said he was having some stomach issues, but there wasn’t much she could do about it. My problem wasn’t until a few days later when he started shaking out of control and wouldn’t stop no matter what I did. A few hours after that, he started bleeding from his nose and eventually collapsed in my arms. I rushed him to the vet but they couldn’t save him. Rimadyl killed my dog.”

“My dog died unexpectedly after being on Rimadyl for less than two weeks. I have been in contact with other pet owners who have had similar experiences.”

Rimadyl killed my dog?

Rimadyl is a safe and effective pain reliever for dogs. However, there is no such thing as a 100% safe and effective drug. All drugs have side effects and some of them can be fatal.

While the FDA has received reports of death in dogs taking Rimadyl, a causal relationship hasn’t been established. Still, there are some factors that increase the risk of death after taking Rimadyl or other NSAIDs.

If your dog takes too much of an NSAID such as Rimadyl, it can cause liver failure, kidney failure, or bleeding ulcers. Some NSAIDs may even be fatal at high doses.

Like other NSAIDs, Rimadyl can cause side effects such as vomiting, diarrhea, and lethargy or lack of energy. However, these side effects are usually mild and short-lived. There is no evidence to suggest that Rimadyl causes death or overdose when taken at recommended doses.

The most serious adverse reactions are liver and kidney damage, gastrointestinal bleeding, seizures, and even death.

Do not use Rimadyl in dogs that are already taking any NSAID medication or dogs with a history of gastrointestinal ulceration or bleeding. Do not use Rimadyl in dogs with liver disease, kidney failure, heart failure, coagulopathies, or hypoprothrombinemia. Do not use Rimadyl during pregnancy or lactation.

How much Rimadyl is safe for dogs?

The recommended daily dosage of Rimadyl for dogs is 2 mg per pound of body weight or 1 mg per pound twice daily, with ongoing evaluation by your vet for the desired effects.

How much Rimadyl is toxic to dogs?

The drug manufacturer does not provide an exact figure for the amount of Rimadyl that is toxic to dogs, but studies have shown that dogs respond adversely to doses of 11 mg per pound of body weight. Additionally, long-term use at therapeutic levels can result in clinical signs of toxicity.

How long does it take for Rimadyl to get out of a dog’s system?

Rimadyl can be given every 12 hours and still maintain its full effectiveness. As with all medications, there are some side effects associated with the use of Rimadyl.

If your dog has been prescribed Rimadyl, be sure that you have read the patient information leaflet and discussed the risks and benefits of using this drug with your veterinarian before administering it to your pet.

What are the side effects of Rimadyl for dogs?

The most common side effects of Rimadyl include vomiting, diarrhea, decreased appetite, lethargy, and weight loss. Although most dogs tolerate the drug well, it can have serious side effects in some dogs, including gastrointestinal problems, liver or kidney damage, and even death.

Rimadyl can interact with other drugs such as steroids and methotrexate. It should not be used together because this combination could lead to severe adverse reactions which can be fatal if not treated quickly and properly.

My dog is acting weird on Rimadyl?

In some dogs, Rimadyl can have side effects that make your pet seem “weird.” These may include changes in mood and behavior.

“My dog has been on Rimadyl for about a year now. She is 11 years old and in pretty good shape but she does have some arthritis. Recently I have noticed her acting strange when she takes her Rimadyl. She shakes, drools, acts lethargic, and sometimes just wants to lay down. My question is, will this pass? Or should I talk to my vet about a new medication?”

“My 11-year-old Lab is on Rimadyl for hip dysplasia. I am concerned because he has been getting up in the middle of the night to go pee, and when he comes back and tries to get back into his bed. He gets so excited to get in his bed that he jumps on it and rolls all over it, which has messed up the sheets (he is a messy dog). Is this normal or should I be concerned about my dog’s behavior?”

“My name is Jenna and my dog, Remi, is a 6-year-old Golden Retriever. He was diagnosed with hip dysplasia shortly after I adopted him from the humane society. Rimadyl was prescribed for his condition, but I have noticed that it makes his personality change drastically. Remi used to be very sweet and gentle but now he tends to bite me when I pet him and he has even growled at me a few times. I am afraid that this medication will make him more aggressive so I want to know if there is any way to treat his pain without using Rimadyl?”

Rimadyl alternatives

Vets may find their patients respond better to Rimadyl alternatives, such as Previcox, Deramaxx, Metacam, Galliprant, or Onsior. All have been shown to reduce pain and inflammation for dogs with osteoarthritis.

Rimadyl reviews from dog owners

It’s not surprising that Rimadyl is one of the most prescribed medications for dogs in the US. Rimadyl reviews are overwhelmingly positive, but some pet owners do warn about potential side effects.

“I am surprised you do not rate Rimadyl higher. My vet prescribed this for my dog who has arthritis and it works great. I tried several other meds and non of them worked. This one does and he also likes the taste so that is a bonus. I am very happy with it and will continue to use it for him.”

“I was a little hesitant to use Rimadyl since it is a prescription drug. After a week, I noticed a difference and I am so happy that I took the chance. My dog has been on it for 2 years and she runs now when we take her out she is very playful. She is now 13 years old and I think the Rimadyl helps keep her active.”

“My dog has chronic hip dysplasia. He’s 10 years old and recently started limping because of the pain. After taking him to the vet, she recommended Rimadyl. Within 2 days, he was back to his normal self! What a relief! Thank you, Rimadyl!”

“This is a long-term solution and not a quick fix. My dog has been on Rimadyl for almost 2 years. He is now 13 yrs old and still plays with his toys, but only for a short time. He does not chase the cats anymore. He walks normally but will stop to smell and pee every few feet. He doesn’t have the strength to pull me when I take him for walks anymore. He cannot jump into the back of my SUV anymore, so I have to lift him up and put him on a raised platform so he can get in easier. As I said earlier, he does not play like he used to but he is still happy and loves to go for walks, I feel guilty when I don’t take him because he looks at me with those sad eyes. If you have an old dog that has been suffering from arthritis, this might be something you want to try. The side effects are minimal and you can always stop taking it if there are any side effects or if your pet is uncomfortable with it.”

Conclusion of Rimadyl toxicity in dogs

Rimadyl is a non-steroidal anti-inflammatory drug (NSAID). It was developed by Pfizer, which continues to manufacture and market it today.

Rimadyl is a prescription medication that can be used to treat dogs with arthritis or other joint problems. If your dog has been diagnosed with osteoarthritis, your veterinarian may have prescribed Rimadyl for him.

Unfortunately, Rimadyl does not come without risks. Many dogs experience severe side effects from the medication, which can include stomach ulcers, kidney or liver disease, and even death.

The FDA recommends that all dogs be closely monitored while taking Rimadyl. This means regular blood tests are needed to make sure the dog’s kidneys and liver are functioning properly and that they don’t have any intestinal problems like bleeding ulcers.

If you decide to give your dog Rimadyl, you should be aware of its potential side effects and monitor him closely for signs of trouble. Speak with your veterinarian about how often he should receive blood work while taking the medication so that you can catch any problems early on before they become serious health issues.

Rimadyl is a safe drug when used according to the instructions of a veterinarian. However, serious side effects can occur when the drug is abused or used incorrectly. The safest way to use Rimadyl for dogs is under the guidance of a knowledgeable veterinarian.

In many cases, the benefits of using Rimadyl for dogs will outweigh the risks. However, it’s important to keep an eye out for any potential side effects and to take action immediately if they occur.

  1. I swear/know that my beloved Rascal died from Rimadyl. What you describe is very similar. He was given Rimadyl in 2015 for basic joint pain (knee). He was only 5 years old. After starting Rimadyl, he started acting catatonic and looking off into space and seemed out of it. Within a few days, he went into congestive heart failure and died. No one could EVER convince me it wasnt the Rimadyl. He was fine with no health problems but for his knee. My crazy, mischievous baby was gone within days of starting Rimadyl. After researching online afterwards, I found that there were far too many others who had similar experiences with Rimadyl. I would demand an alternative medication. My current 13 year old border collie takes Galliprant with no side effects and demonstrated arthritis pain relief.

  2. Our six year old lab passed away 11 days after surgery. She was prescribed Carprofen for the pain. We noticed her symptoms one week after surgery: vomiting, droopy eyes, disorientation. We took her back to the vet for observation and blood work. Bloodwork was normal and they had no explanation and never recommended a new medicine. In the next couple of days she would randomly get disoriented but seem to come out of it. We tried contacting our vet but were unable to speak to a doctor. On her fourth day of active symptoms she was completely out of it, walking into walls and full on disorientation. After, she had what seemed to be a seizure and still fully disoriented, no longer coming out of it, we took her to the emergency vet and they prescribed a new pain med and muscle relaxer. Again, no explanation. We brought her home and the new medication sedated her. She had more seizure like episodes every 15/20 minutes. We were unable to wake her and she passed away on the way back to the emergency vet. The doctors never knew the cause. We believe it was the medication that we now know has taken so many other pups far too early.
