But beneath the fur, scales, and feathers lies an intricate inner world that often holds the key to a diagnosis long before a lab result confirms it. That world is behavior.
Animals are evolutionarily hardwired to hide weakness. In the wild, showing pain is an invitation to predators. This means that by the time a dog limps, or a cat vocalizes, the pathology is often advanced. In veterinary medicine, we’re trained to look for
We now have the physiological data to prove that chronic stress kills. When an animal experiences fear or frustration (e.g., from lack of environmental enrichment, social conflict, or painful handling), the hypothalamic-pituitary-adrenal (HPA) axis floods the body with cortisol.
