Today, the intersection of represents one of the most critical frontiers in animal welfare. It is no longer enough to treat the body; the modern veterinarian must also understand the mind. The Medical Roots of Behavior One of the most significant contributions of veterinary science to the study of behavior is the understanding that "bad" behavior is often a symptom of underlying pathology. Where a layperson might see a dog that is suddenly aggressive or a cat that has stopped using the litter box, a veterinarian sees a potential medical crisis.

For example, a dog with severe separation anxiety may be in such a state of panic when left alone that they injure themselves trying to escape.
