Critical periods in early life (pre- and postnatal) that shape an animal's future social competence and reactions.

: Breakthroughs such as non-contact, video-based heart rate monitoring allow veterinarians to assess stress levels without restraining the animal. This technology facilitates "fear-free" examinations, reducing the risk of injuries to both staff and patients. Welfare and Precision Management

In one landmark study, over 60% of dogs referred for aggression had an underlying medical condition contributing to the behavior. The lesson is clear: You cannot train away a thyroid problem.

Historically, veterinary curricula devoted minimal time to ethology (the science of animal behavior). The focus was on pathology, pharmacology, and surgery. Behavior problems were frequently dismissed as "bad manners," "dominance issues," or simple "stubbornness."
