Your vet can prescribe painkillers for your pet. If you think your pooch is in pain, schedule an appointment with your vet as soon as possible. Be specific with the symptoms you are noticing, to help your vet to diagnose your dog's condition. Depending on the cause of your dog's pain, your vet may prescribe Carprofen, Deracoxib, Firocoxib, or Meloxicam to manage their symptoms. A vet may also prescribe off-label painkillers like paracetamol for your dog. You must follow the directions that your vet gives you if your dog is given painkillers. Even if the painkiller is made especially for dogs, it is still possible to overdose your pet on the painkiller. Furthermore, painkillers for dogs can cause side effects that must be closely monitored.
