Why Choose K9one at Stonehill Kennel

Experience that matters. Founder Chris Byrne led K-9 bomb detection at the World Trade Center recovery mission after 9/11 and has trained dogs and handlers for law enforcement, the military, and the entertainment industry.

Serious behavior solved. We rehabilitate aggressive, fearful, and anxious dogs and support owners for the long term. 

Balanced, fair training. We use proven methods grounded in phycology, conditioning, motivation, timing, and consistency. 

All breeds welcome. From puppies to powerful working breeds, we’ve seen and trained it all.

 

Lifetime guarantee. Graduates of our six-week program are covered for life on the exercises we teach.

 

Trusted by the highest levels of service, focused on your dog.

 

K9One’s foundation comes from training and supplying dogs for the NYPD, U.S. Department of Defense, and major law-enforcement agencies, with experience rooted in the World Trade Center Recovery Mission. Today, we use that same structure and clarity to help family dogs become calm, reliable companions, using balanced, humane methods we stand behind for life.

"Absolutely the best dog care anywhere. My dogs went through the board and train program to come out amazing. The care & professionalism from the staff is second to none and we won’t ever go anywhere else."

 

Sabina Martinelli

"I can't say enough great things about Stone Hill Kennel and especially our trainer, CJ. If you're looking for a knowledgeable, dedicated, and professional trainer who truly cares about your dog's success, I highly recommend CJ at Stone Hill Kennel."

David Collerd

"We cannot recommend K9One enough! It was as Chris promised, "transformative," for our puppy, but also for us. The investment you make in training your dog will definitely pay off long-term for you, your dog and your family."
