One of the most significant advancements in modern veterinary science is the recognition that abnormal behavior is often a clinical sign of an underlying physical disease. The old paradigm assumed that a cat urinating outside the litter box was "spiteful" or a dog chewing furniture was "bored." The new paradigm, driven by behavioral science, asks: What hurts?

Animal behavior is not a separate subspecialty but a core component of veterinary science. Behavioral observation improves diagnostic accuracy, reduces stress-induced physiological artifact, guides safe handling, and enables effective treatment of common behavioral disorders. Veterinary curricula must expand behavioral training, and practitioners should adopt low-stress handling as a standard of care. Ultimately, integrating behavior into every veterinary interaction enhances both medical outcomes and the human-animal bond.

Behaviorally-informed handling protocols—using minimal restraint, positive reinforcement, and environmental modifications (e.g., non-slip surfaces, hiding places, feline pheromone diffusers)—have been shown to:
