Certified applied animal behaviorist

A behavior specialist certified by the Animal Behavior Society, normally holding a doctorate and years of experience, who treats behavior problems.

Also called: CAAB, applied animal behaviorist, Animal Behavior Society certification

A certified applied animal behaviorist, or CAAB, is certified by the Animal Behavior Society. The certification requires an advanced degree in behavior science, usually a doctorate, or a veterinary degree plus a residency in behavior, together with supervised experience and continuing education. Associate certification, called ACAAB, exists for those with a master's degree.

A CAAB studies and treats behavior problems in companion animals, using science-based assessment and behavior modification. They work with owners and often with veterinarians.

A CAAB is not a veterinarian unless they also hold a veterinary degree, so they cannot prescribe medication. A board-certified veterinary behaviorist, with the letters DACVB, can. For serious problems such as aggression, many owners start with a veterinarian and then seek a CAAB or DACVB for a plan.
