While acute stress keeps animals alive in the wild, chronic stress damages the body. In shelter dogs or confined livestock, prolonged high cortisol levels suppress the immune system, slow down wound healing, and alter brain structure, leading to severe behavioral depression or stereotypic behaviors (like pacing or cribbing). 4.

For cows and pigs, behavior is the gold standard of welfare assessment. A lame dairy cow doesn't just look sad; she changes her lying down and standing up patterns. She spends less time at the feed bunk. By quantifying these behavioral changes using accelerometers (Fitbits for cows), veterinarians can detect lameness 48 hours before it is visible to the naked eye. This is the marriage of high-tech data and classical behavioral observation.
can signal chronic pain, dental disease, or arthritis.
Veterinary behaviorists apply these principles to treat behavioral disorders that might otherwise lead to rehoming or euthanasia.
