Perhaps the most profound shift is in the treatment of chronic pain. For decades, lameness exams focused on gait analysis at a trot. Today, ethologists have taught veterinarians to read the subtler lexicon of pain: a slight tension in the brow of a rabbit, a refusal to jump onto a sofa (rather than a yelp), the "prayer position" of a dog with pancreatitis. By treating the behavioral expression of pain as valid data, veterinary science has opened the door to multimodal pain management that includes environmental modification, physical therapy, and nutraceuticals alongside traditional NSAIDs.

Veterinary science has made massive strides in psychopharmacology. Medications like SSRIs (Selective Serotonin Reuptake Inhibitors) are now used alongside behavioral training to treat severe anxiety and OCD in animals. Understanding the neurobiology of the animal brain allows veterinarians to prescribe treatments that rebalance brain chemistry, making training and rehabilitation possible.
