Veterinary approaches to pain management in animals have changed over the past few decades from believing pain was necessary for healing to treating animals until certain they are no longer in pain, as animals cannot verbalize their pain. Veterinarians have several options to treat animal pain, including NSAIDs, analgesic gels, and when drugs and massage are insufficient, alternative therapies like acupuncture. Careful monitoring of an animal's behavior is important to determine if it is experiencing pain.
