C.H.A.C.O. Dog Training & Behavior Consulting’s approach to dog training and behavior modification is based in the behavioral sciences. While working together, C.H.A.C.O. will diagnose the problem based on knowledge of learning theory and observations of your dog rather than relying on interpretation. For example, they might notice that the dog is barking and snarling at other dogs when he is on leash, but he plays nicely when he is off leash. This observation suggests that the dog is leash- reactive, which is a specific type of aggression. After discussing your goals and observing your dog’s behavior, C.H.A.C.O will: give you relevant information about your dog’s behavior; suggest management techniques to give you some immediate relief from the situation and to stop the dog from practicing (and perfecting) the behavior that you want to change.
