A dairy veterinarian knows that a cow’s behavior predicts illness 48 hours before a fever appears.

We are entering a new era of data-driven behavioral veterinary science. Wearable technology—Fitbits for pets—now tracks sleep cycles, heart rate variability, and scratching frequency.

Animal behavior is the study of the actions and reactions of animals in response to their environment, social structures, and learning experiences. It encompasses a wide range of topics, including communication, social behavior, learning and memory, and emotional experiences. By understanding animal behavior, researchers and veterinarians can gain insights into the cognitive and emotional lives of animals, which is essential for providing optimal care and improving their welfare.

As veterinary science advances, the field is looking closer at the genetic and molecular roots of behavior. Behavioral genomics aims to identify specific gene markers associated with traits like noise phobia, impulsivity, and social anxiety.
