Major Interest in Animal Behavior

My major daily interests are clinical behavioral medicine for dogs and research into the effects of early development on dog and cat behavior and brain development, neurobehavioral genetics, and genetics of anxiety disorders in dogs. My long-term interests are to establish the field of veterinary behavioral medicine as one that is equal to other specialties in veterinary medicine and one that is based firmly on data and an understanding of underlying mechanisms of the conditions that we treat.

I edit the journal in the field, Journal of Veterinary Behavior: Clinical Applications and Research, and have written 2 of seminal texts in the field: Veterinary Behavioral Medicine for Small Animals and Manual of Behavioral Medicine for Dogs and Cats.

Explanation of Credentials

DVM or VMD (Doctor of Veterinary Medicine or Veterinary Medical Doctor) Veterinarians are qualified to diagnose and treat medical and behavioral problems in animals. They are the only professionals who can prescribe medications to treat such problems. Some veterinarians have a special interest in behavior and limit their practices to behavior medicine.

DACVB (Diplomate of the American College of Veterinary Behaviorists) These veterinarians are board-certified specialists with extensive post-graduate training in animal behavior. DACVBs are qualified to diagnose and treat medical problems in animals, including prescribing medications and behavior modification plans to treat these conditions.

PhD (Individuals who have completed a PhD degree in animal behavior or a related field) This degree is research and theory related, and requires contributions to the animal behavior literature. These consultants cannot prescribe medications but often work closely with a veterinarian who can.

CAAB (Certified Applied Animal Behaviorist) These individuals have completed a graduate degree in animal behavior or a related field and have research experience as well as clinical experience working with animals. CAABs are qualified to evaluate and manage behavioral problems in animals, but cannot prescribe medications. They typically work closely with a veterinarian who can.

Note: In order for a veterinarian to prescribe medication, a valid doctor-patient relationship with the animal is required. This requires a current examination (within the past year) of the patient, and direct involvement in the treatment plan. This evaluation should include the report and suggestions from other professionals who have evaluated the pet (CAABs, PhDs, trainers, or other veterinarians).
