Veterinary schools, for most of the 20th century, dedicated surprisingly few hours to behavior. The prevailing logic was simple: a veterinarian treats disease; a trainer or owner manages behavior. If a dog barked excessively, it was a training problem. If a horse refused a jump, it was a riding problem.

When a veterinarian understands that a growl is a symptom, not a personality flaw, they treat the patient differently. When an owner understands that a house-soiling cat is not vengeful but sick, they seek help sooner. When a farmer understands that a stressed pig is a less productive pig, they change their management.

This division caused a dangerous diagnostic blind spot. Veterinarians would treat a cat for "idiopathic cystitis" (bladder inflammation with no known cause) without asking about the new puppy in the house. They would prescribe antibiotics for a dog’s chronic diarrhea without investigating separation anxiety.

The integration of into mainstream veterinary science is no longer a niche specialty; it is becoming the standard of care. From reducing stress-related illnesses to improving diagnostic accuracy and ensuring human safety, understanding why an animal behaves the way it does is now as vital as understanding its white blood cell count.

Veterinary Workup: Physical exam, bloodwork, and thyroid panel were normal.
