Amazing!!! Went from biting and leash pulling none stop, to now a behaved puppy who listens to commands. Consistency is key. Everyday walks, taking him for rides, and public places are so much easier. We’re so thankful for all the help and continued guidance for Sunny.

Tristan did an amazing job training my dog orbit. He corrected several negative behaviors, most significantly barking incessantly and begging. It is unbelievable how Tristan trained orbit to walk nice on a leash, even when other dogs are on the walk. With the simple instruction to go climb, he now...

We had a great experience with Tristan during our dog’s two-week training program. Our dog came back trained, more focused, and a stronger foundation for us to build on at home. Tristan also provided a very thorough two-hour follow-up training session, where he explained everything clearly and gave...

I can’t recommend Tristan highly enough! We sent our dog, Skoda, for a two-week board and train program and the results exceeded every expectation. In just two weeks, Skoda learned an incredible amount. His confidence, obedience, and focus have improved so much, and it’s obvious that Tristan knows...

What an exceptional and excellent trainer. We had our newly adopted 2yr old belgian malinois do a 2 week board and train and she came back with great manners and learned quite a bit. Also helped with agressiveness and ability to be calm around other dogs.Even cats it seems as one ran in my backyard...

A couple years ago, we decided to get a blue heeler puppy (Spooky). When she turned about 1 year old, we lost all control of her behavior and she was a WILD one. I wanted to give her to a farm, however my husband met Tristan at HBOT therapy and told him about Spooky and her crazy/hyper behavior....

Tristan was amazing with our dog, Gus! Super friendly, easy to work with, and great communication. He taught Gus so well. Would absolutely send another dog to be trained by Tristan!
★★★★★
I can't say enough excellent thi gs on how great of a trainer Tristan is. I got a 2 year old Belgian Malinois that was very high strung and would jump 7 ft in the air chasing shadows. It was so hard to deal with. But, after 2 weeks with Tristan it's like we have a whole new dog. A better dog. She...
★★★★★
5 stars doesn’t do justice for the absolute amazing job the K9 Lab did with training my 7 month old dog reactive pup, Elsi. When I first talked to Tristan, I expressed my frustrations with walking Elsi. She was extremely dog reactive and would pull every time we would walk outside. I love her, but...
★★★★★
Our rescue dog’s behavior was getting so bad we didn’t know if we could keep her. She was becoming a liability to have in our home. We reached out to The K9 Lab as our last hope. Old dogs can learn new tricks. Our pup is a very stubborn, grouchy old lady and her trainer worked the miracle we...

Our Programs
Your dog stays with Tristan and his team for personalized attention and daily training, then comes home ready.
Reactivity, anxiety, biting, nipping and aggression toward people or other dogs.
Biting, jumping and leash pulling handled early, with the foundations your puppy keeps for life.
Why The K9 Lab
Tristan and his team teach you the secret to communicating with your dog, so commands are both understood and have meaning. A trained dog only stays trained if the owner knows what to do.
A clear routine and clear expectations every day. Consistent structure is what makes commands stick fast and keeps good behavior going long after training ends.
A better behaved dog, backed by a guarantee. We tell you honestly what it will take to get there before you commit to anything.
Recall, loose leash walking and staying calm around people and other dogs. Sit, down, place and heel that work at the park and the patio, not just the living room.
You leave with a new daily routine that meets your dog's needs and reinforces every skill, so the training carries over into real life at home.
All breeds and all behaviors. Reactivity, anxiety, biting, excessive barking, pulling, jumping and aggression, with a program tailored to your individual dog.
