Professional Private Dog Training Where Real Life Happens
Every dog has the potential to become a calm, confident, and enjoyable companion. The key isn't finding the perfect dog—it's building better communication.
For more than 30 years, I've helped families throughout Mercer County strengthen the relationship they share with their dogs through private, personalized at-home training.
I'm John Wasilishen, Owner and Master Trainer of ProDogK9.
Every lesson is taught by me. Every program is customized. Every session takes place where your dog actually lives and learns.
Whether you're raising a puppy in Princeton, working with a rescue dog in Hamilton, or helping an energetic adolescent in Hopewell, my goal is simple: give your family the tools to enjoy life together.
Welcome to the ProDogK9 State of Mind. Every Dog. Every Time.
Why Mercer County Families Choose ProDogK9
Mercer County offers an incredible variety of lifestyles. Historic neighborhoods, suburban communities, college towns, parks, and larger rural properties all create unique distractions and opportunities for dogs to learn.
That's why I don't believe the best training happens inside a building.
It happens at home.
Your dog learns where they greet visitors, walk your neighborhood, relax with your family, and experience everyday life.
Private at-home training allows me to address real behaviors in real situations while coaching every member of your family to communicate consistently.
Since 1993, that philosophy has helped thousands of New Jersey families enjoy calmer homes and happier dogs.

Breed Spotlight: German Shorthaired Pointer
German Shorthaired Pointers are athletic, intelligent, and full of enthusiasm. They're incredible companions for active families but require both physical exercise and mental engagement.
Without guidance, that energy often becomes pulling on leash, jumping, chasing wildlife, and difficulty settling indoors.
I help owners channel that drive into focus, self-control, and dependable obedience while preserving the breed's outgoing personality and love for adventure.
Real Success Stories
-
⭐ Goldendoodle Making Incredible Progress
-
One Mercer County family contacted me after struggling with their energetic 1½-year-old Goldendoodle.
-
After just one private lesson, they shared:
-
"We just finished our first session with John and our 1½-year-old Goldendoodle and we are so excited for our next session already. John gave us really good tips and information. We can see a difference with her already. Highly recommend!"
-
Sometimes the biggest breakthrough isn't teaching another command—it's helping families communicate in a way their dog finally understands.
-
⭐ Puppy Ruby's Transformation
-
Ruby was only three months old when her family reached out.
-
Jumping.
-
Biting.
-
Grabbing clothes.
-
Complete puppy chaos.
-
After beginning Puppy Foundations, her owner wrote:
-
"John took control of the situation immediately. Ruby quickly gained respect. She sat, laid down, listened, stopped jumping and became well behaved right before my eyes. John exceeded my expectations."
-
Early training creates lifelong habits, and that's why I encourage families to start as soon as possible.
