For decades, veterinary medicine was primarily a field of physiology. The focus was on the palpable: broken bones, parasitic infections, organ failure, and tumors. If an animal was brought to the clinic for “acting strange,” the standard protocol was to run a blood panel, check vitals, and look for a biological culprit.

Veterinary medicine has evolved far beyond treating physical injuries and biological illnesses. Today, the integration of animal behavior and veterinary science represents one of the most significant advancements in animal welfare and clinical practice. Understanding how an animal interacts with its environment, communicates distress, and processes stress is now recognized as vital to providing effective medical care.
