TJ’s Journey: From Passion to Profession
TJ’s career began in dog rescue and rehabilitation, working hands-on with neglected, fearful, and aggressive dogs that others had given up on. Over time, he developed a structured approach that blends motivation, accountability, and real-world exposure, ensuring dogs can function in any environment.
“I’ve worked with everything from abandoned strays to high-drive working dogs—and one thing remains true: Dogs thrive when given clarity, structure, and the right motivation.”
Today, TJ is known for turning around dogs that others have deemed “untrainable.” His ability to read, assess, and rehabilitate even the most extreme behavior cases has made ZRO DFX K9 a go-to resource for dog owners seeking real results.
TJ’s Training Philosophy:
Clarity, Motivation, Accountability
A Balanced Approach Rooted in Science & Real-World Success
Unlike traditional trainers who rely solely on either positive reinforcement or harsh corrections, TJ’s training philosophy is built on operant conditioning, ensuring clear communication between dog and owner.
​
3 Core Pillars of TJ’s Training:
​
-
Clarity – Dogs need consistent, structured communication to learn effectively.
-
Motivation – Training should be reward-based and engaging, tapping into each dog’s natural drives.
-
Accountability – Balanced training means providing both rewards and structure for real-world reliability.
