Sentinel K9 is a veteran-owned dog training and boarding company serving Fort Worth, Argyle, and the greater DFW area. Founded by U.S. Army National Guard officer Chandler Hunt, we bring military discipline and a boutique, high-touch standard to every dog we train. Our structured board-and-train programs cover everything from puppy foundations to advanced off-leash obedience, behavior rehabilitation for aggression and reactivity, and individually task-trained service dogs for seizure response, mobility, autism, and PTSD support. Every program includes private owner lessons, daily updates, and a written progress report — because the goal isn't a trained dog for three weeks, it's a calm, reliable partner for life. With 500+ dogs trained and a 5-star reputation, we treat your dog like our own.
