JW Dog Training & Behavior provides professional, expert dog training and behavior support to the Washington, D.C. area. We specialize in one-on-one lessons with clients, working in the client’s home to thoroughly address behavior issues and build skills.


Training sessions are fun and low stress for both the dog and human. Using the science of learning, with an emphasis on positive reinforcement, we create effective, easy-to-follow training plans that are designed to make dogs and their owners successful.


We use force free, science-based methods when working to change behavior, including clicker training, play, real life rewards, management, and more. We focus on building and reinforcing desirable behavior, while also implementing structure and management to decrease undesirable behavior. We tailor our training plans to the individual client's needs, whether it is basic manners or a more complex behavior issue such as fear, anxiety, leash-reactivity, or aggression.


We teach human clients how to better understand their dogs’ behavior and communication, and help them improve their training skills to more effectively work with their dogs and see better results.
