Animal Behavior

Aggression describes behavior occurring in particular circumstances, not necessarily a fixed personality trait. Depending on the species and circumstances, fear, conflict, pain, resource guarding, territorial circumstances, previous learning, arousal, or other factors can contribute to aggressive responses. In dogs, for example, veterinary behavioral guidance cautions against using an aggressive act alone to characterize temperament and emphasizes behavioral history, environment, triggers, and the target of the behavior when assessing aggression.

Yes. Pain, neurologic disease, sensory impairment, and other medical conditions can alter an animal's responses or contribute to fear, irritability, or aggression. When the evidence suggests a possible medical component, veterinary expertise may be needed alongside behavioral analysis. Board-certified veterinary behaviorists are veterinarians with specialized training in evaluating how an animal's health, environment, experiences, and behavior may interact.

Useful materials may include incident video and photographs, witness statements, veterinary records, training records, adoption or acquisition history, prior behavior complaints, bite or attack reports, animal-control records, housing and confinement information, correspondence about earlier incidents, and records identifying who handled the animal and under what circumstances. For behavioral reconstruction, contemporaneous records can be particularly useful because behavioral assessment depends on accurately describing what occurred before, during, and after the event, while later witness or owner descriptions may be more subjective than contemporaneous video and should be considered alongside other contemporaneous records.
