Animal behavior is a critical aspect of veterinary science, as it provides valuable insights into an animal's physical and emotional state. Behavior is a primary indicator of an animal's health, and changes in behavior can signal underlying medical issues or stress. For instance, a decrease in appetite or a change in social interaction can be indicative of pain, illness, or anxiety.

For instance, sudden aggression in a senior dog may not be a personality change but a reaction to or cognitive dysfunction.
