The study of animal behavior and veterinary science extends far beyond pets. It encompasses livestock, wildlife, and laboratory animals under the "One Health" initiative, which recognizes that human, animal, and environmental health are interconnected.

Veterinary science helps differentiate whether these actions are purely psychological or triggered by dermatological allergies and neurological lesions. 3. Fear-Free and Low-Stress Handling Practices
