To understand behavior, one must first understand biology. Every action an animal performs—from a dog’s compulsive tail chasing to a cat’s sudden aggression—is rooted in neurochemistry, endocrinology, and genetics.
The American College of Veterinary Behaviorists (ACVB) and European equivalents represent board-certified specialists (Diplomates) who are first trained as veterinarians, then complete a residency in behavior.
They treat complex cases such as:
Behavior is also the frontline defense against disease transmission. A dog that is aggressively reactive to strangers may not receive adequate veterinary care because no one can safely examine it. This neglect leads to untreated dental disease, parasites, and vaccine-preventable illnesses.
Conversely, behavioral changes can signal diseases that threaten human health:
Veterinary scientists increasingly train practitioners to perform a behavioral triage during every intake: Is this animal acting normally for its species, breed, age, and history? If not, we must ask: Is it a brain problem, a body problem, or both?
