We now know that specific genes (e.g., the serotonin transporter gene SLC6A4) are linked to impulsivity and aggression in dogs. A genetic test can tell a breeder or veterinarian that a puppy is predisposed to anxiety. This allows for preventative behavioral veterinary medicine—starting socialization and habituation protocols from day one, before maladaptive circuits are wired.
Stress is the most common behavioral driver in a clinical setting. When an animal perceives a threat—a stranger in a white coat, the cold steel of a stethoscope, the smell of a kennel—the hypothalamic-pituitary-adrenal (HPA) axis activates. Cortisol and adrenaline surge. While this "fight or flight" response is adaptive in the wild, chronic activation in a veterinary setting leads to "learned helplessness" or aggression. We now know that specific genes (e

Consider taking a dog’s temperature rectally. A calm dog has a normal temperature of 101.5°F. A terrified, struggling dog can spike a temperature of 103.5°F due to muscle exertion and stress hormones. This iatrogenic hyperthermia could lead a vet to falsely diagnose a fever and prescribe antibiotics that are not needed. While this "fight or flight" response is adaptive
Similarly, a cat that is held in dorsal recumbency (on its back) for an abdominal palpation will often freeze. A novice interprets this as "calm." An expert knows this is "tonic immobility"—a fear response based in the brainstem, identical to a rabbit freezing when a hawk approaches. The cat’s heart rate is 250 beats per minute, but it isn't moving. Relying only on the lack of movement (behavior) without understanding its physiological meaning leads to a misdiagnosis of "cooperative."
The most common reason cats are surrendered to shelters is inappropriate elimination. A pure veterinary approach might prescribe antibiotics for a urinary tract infection (UTI). But a behavioral approach asks: Is the litter box clean? Is it in a high-traffic area? Is there a new stray cat outside the window causing anxiety?
