Zak Kergel, the trainer behind KompK9
About Zak Kergel

The story
behind KompK9

How a reactive 130 pound Bullmastiff named Titus turned Zak Kergel into a trainer, and why KompK9 stands for Comprehensive Canine.

The origin

It started with Titus

I have always loved dogs, and I thought I understood them. Then we brought Titus home. The plan was to raise a sweet, dopey Bullmastiff into a dog everybody enjoyed. What I ended up with was a very reactive, 130 pound problem I did not know how to handle.

That apparent disaster turned out to be a blessing. I spent hundreds of hours on training videos and behavior articles, tried things, failed, adjusted, and slowly Titus improved. So did I. Watching him change lit the fuse. I took an internship to keep learning about dog behavior, and just as important, about teaching owners. Eventually all of it became KompK9.

I tell every behavioral client the same thing: I am not describing your dog from a textbook. I lived with the lunging, the embarrassment, and the quiet fear that this was just my life now. It was not, and it does not have to be yours either.

The name

What Comprehensive Canine means

KompK9 is short for Comprehensive Canine. The name was my wife's idea, and it describes the method. Behavior does not happen in a vacuum, so I do not train in one. Every program looks at the whole dog: training, diet, the tools you use, and the environment your dog lives in. When those four line up, the results stay.

It is the difference between a trainer who teaches commands and a dog behaviorist mindset that asks why the behavior is happening in the first place.

How I work

Discipline from the Air Force, patience from the dogs

I served 23 years in the U.S. Air Force and retired as a Master Sergeant. That career shaped how I work: show up on time, stay calm under pressure, follow the plan, and adjust when the plan meets reality. Dogs respond to that kind of consistency. So do their owners.

Professional standards

A Professional member of the IACP

I am a Professional member of the International Association of Canine Professionals, a professional association for dog trainers founded in 1999. The IACP advances the profession through education and professional development, keeps a code of conduct and ethics, and defends a trainer’s freedom to choose the tools and methods that fit the dog.

That last part is how I work. Every program uses what your dog actually needs, from first commands to off-leash e-collar training, and I will always explain exactly what and why.

Faith and family

It's a family thing

KompK9 is a small, Christian owned family business, and Colossians 3:17 is part of our logo for a reason. This business is built on faith, family, and doing right by people and their dogs. Staying small is a choice. You will always deal with me directly, and your dog will always be trained by the person you actually hired.

And whatsoever ye do in word or deed, do it all in the name of the Lord Jesus, giving thanks to God and the Father by him.

Honestly, and with the dog in front of me

That is how I train. I use what your dog needs, I explain why, and I teach you to do everything I do, because a dog stays trained when the owner knows what they are doing. My favorite messages are the photos that come months later: a dog lying calmly at a brewery, or hiking off leash, long after our last session. That is the goal from day one. Enjoy your dog again.
