Veterinarians use ethograms (behavioral repertoires) as diagnostic tools.

One of the hardest lessons in veterinary science is that absence of behavior is not absence of pain. Prey animals, including dogs, cats, and horses, evolved to hide weakness. In the wild, showing pain meant becoming a target. One of the hardest lessons in veterinary science
This "masking" behavior has profound clinical implications. A dog with chronic osteoarthritis may not limp or yelp in the exam room. Instead, a keen observer must look for subtle behavioral shifts: Veterinarians who are fluent in behavioral science are
Veterinarians who are fluent in behavioral science are better equipped to diagnose these cryptic pain states and initiate multi-modal pain management plans that include both drugs (NSAIDs) and behavioral modifications (ramps, orthopedic beds).
Punishing a growl does not remove the fear; it removes the warning. The dog learns to bite “without notice.” This is how many “sudden, unprovoked attacks” actually begin.
