A board-certified veterinary behaviorist is a veterinarian with advanced specialty training in behavior medicine who has been certified by the American College of Veterinary Behaviorists (DACVB)—think of them as pet psychiatrists. During their training, veterinary behaviorists complete a residency, extensive casework, publish research, and pass a board exam. Their expertise includes medical and behavioral knowledge, allowing them to treat issues like anxiety, aggression, phobias, and compulsive behaviors.
