Rimadyl for Dogs
Rimadyl is a nonsteroidal anti-inflammatory drug that is very helpful for pain and fever relief, and for inflammation in canines suffering from osteoarthritis (OA). Rimadyl is also used to control pain during and after surgeries such as spaying or ear procedures.
OA affects dogs, both young and old. 25% of the canine population has osteoarthritis. The pain can bring a lot of discomforts, and that is why NSAIDs are highly recommended. Rimadyl is FDA-approved for dogs as young as 6 weeks old. Read below for helpful information on the efficacy, side effects, and considerations for Rimadyl.
