Arthritis
Nonsteroidal anti-inflammatory drugs, or NSAIDs, help reduce swelling, stiffness, and joint pain in humans, and they can do the same for your dog. They can bring relief to a dog with arthritis, or one who's just had surgery. ... There are some of the available NSAIDs just for dogs.
All dogs and cats should undergo a thorough history and physical examination from a vet, before beginning NSAID therapy.
