This integration, however, remains incomplete. The greatest challenge facing the field is structural. Most veterinary curricula still dedicate a paltry number of hours to behavior, leaving practitioners ill-equipped to handle common but complex cases like inter-dog aggression or feline house-soiling. The result is a public health crisis: behavior problems are the single leading cause of euthanasia for young, physically healthy dogs and cats. Owners surrender or put down animals not because of incurable disease, but because of manageable behavioral issues—barking, scratching, biting—that the veterinary profession has historically been ill-trained to address. Bridging this gap requires a fundamental reimagining of veterinary education, embedding behavior not as an elective but as a core clinical science, from the first year through residency.
