When a veterinarian ignores behavior, they miss critical diagnostic data. Sudden aggression in a docile dog might not be a "discipline issue"; it could be a sign of hypothyroidism or a brain tumor. A cat urinating outside the litter box may not be "spiteful," but suffering from interstitial cystitis or arthritis that makes climbing into the box painful.
Behavioral issues are the number one cause of euthanasia in dogs and cats under the age of three, surpassing infectious diseases and cancer. This is a tragic statistic that veterinary science is uniquely positioned to combat. When veterinarians are educated in behavioral pharmacology and modification plans, they can save lives.
This integration requires the veterinarian to treat the "pet-client bond." If a dog has separation anxiety, the owners suffer sleep deprivation, property damage, and social isolation. By treating the animal's behavior, the veterinarian preserves the integrity of the home, preventing the animal from being surrendered to a shelter. In this way, veterinary behavior is preventative medicine for the society of pets. While companion animals drive much of the conversation, the marriage of behavior and veterinary science is arguably even more critical in zoological and wildlife settings. Here, the animal cannot tell you where it hurts, and physical restraint can be life
The integration of ethology (the scientific study of animal behavior) into veterinary practice allows for differential diagnoses that physical exams alone cannot provide. It transforms the veterinary professional from a mechanic fixing a machine to a holistic healer treating a sentient being. One of the most compelling arguments for integrating behavioral science into veterinary practice is the physiological impact of stress. The veterinary environment itself—a clinic—is often a trigger for high arousal and fear in animals.
