Not all OTC pain relief for dogs is safe. Do not give your dog ibuprofen or acetaminophen. Nonsteroidal anti-inflammatory drugs, or NSAIDs, help reduce swelling, stiffness, and joint pain in humans, and they can do the same for your dog. Such as carprofen(Novox or Rimadyl); deracoxib (Deramaxx); firocoxib (Previcox); meloxicam (Metacam );
But sometimes, your dog may need more options. Your vet may discuss gabapentin or tramadol with you.
