When an animal experiences fear or anxiety—whether from a painful exam, loud kennels, or the smell of predators—the body releases cortisol and adrenaline. Short-term, this is adaptive. Long-term or acute severe stress leads to:
The modern shift occurred when clinical professionals realized that behavioral changes are often the first indicators of underlying physical illness. Consequently, Veterinary Behavior has emerged as a recognized board-certified specialty. This specialty focuses on the prevention, diagnosis, and treatment of behavior problems in companion, agricultural, and laboratory animals. How Behavior Signals Physical Illness

Habituation occurs when an animal stops reacting to a harmless, repeated stimulus, like traffic noise. Sensitization happens when a stimulus causes an increasingly intense reaction, such as a worsening fear of thunderstorms. Behavioral Signs of Medical Issues
Traditionally, a veterinarian might look at heart rate, respiratory rate, and temperature as the "big three" vital signs. However, a growing body of research suggests that should be considered the fourth vital sign.
