About True North Canine

Veteran-owned training in Celina

True North Canine is a veteran-owned dog training business at 608 W Main St in Celina, serving Celina, Prosper, Frisco, McKinney and communities across DFW and North Texas. Owner and head trainer Patrick Mullooly is a U.S. Marine Corps veteran with 8+ years training dogs, from family pets and shelter dogs to law enforcement K9s, military working dogs and Special Operations Multi Purpose Canines.

Approach

Patrick builds training on structure, clear communication, consistency and owner education, aiming for lasting results and real-world off-leash reliability rather than quick fixes.

Programs

Board and train runs 3, 4 or 6 weeks with the dog living and training with True North. Private lessons are one-on-one in-home coaching across DFW, and virtual lessons offer live video coaching. Behavior modification for aggression, reactivity and fear is a specialty. Graduates get lifetime access to weekly group lessons at no extra fee.

What owners say

One owner wrote that after a year of severe dog reactivity, "just a few sessions with Patrick, the difference is night and day."
