In the wild, showing weakness is a death sentence. Despite thousands of years of domestication, dogs, cats, rabbits, and horses retain the instinct to mask pain and illness. This is where veterinary science relies heavily on behavioral observation.

Understanding behavior is essential for modern veterinary practice. For example, veterinarians use behavioral cues to identify pain in non-verbal patients or to manage stress in clinical settings. Educational programs, such as those at the University of Wyoming

Endocrine disorders, such as hyperthyroidism in cats or Cushing’s disease in dogs, can cause extreme restlessness, vocalization, and anxiety-like symptoms. The Evolution of the Low-Stress Clinic

This involves positive reinforcement (adding a reward to repeat a behavior) and negative punishment (removing something desirable to stop a behavior).
