Testimonials
Easily the best dog training you can get, and its worth every penny! Dillon was great! We have 2 japanese akitas and the younger one had some bad habits. With Dillons help we stopped barking and socialized safely. He not only helped us train better habits but also helped us understand our fur babies better and taught us how to train beyond the sessions. Everything was customized to our dogs and us.

We recently had the pleasure of working with Dillon to help train our two Cane Corso puppies–aka our little (but actually massive) mini horses–and the experience was phenomenal.
From day one, he was incredibly informative, patient, and hands off so we were in control and learning rather than him just doing it. He didn’t just teach our pups–he taught us how to understand and communicate with them better. His approach was structured yet flexible, adapting to each of our dogs’ personalities while still maintaining firm and clear expectations.
Thanks to his guidance, we now feel so much more confident and equipped to raise well-behaved, obedient, and socialized Cane Corsos. We still have growing to do (literally and figuratively!), but we’re now on the right path and it’s all thanks to his help.
Highly recommend to anyone looking to turn chaos into calm–even if your “puppies” are the size of small horses!
– Client
We could not be happier with the results from Dillon’s help training our Belgian Malinois.
We were told by others that we were “crazy” for getting a breed as demanding as a Malinois (someone even begged us to get in touch the breeder and call the whole thing off). The first few months, before working with Dillon, we got a glimpse into why people felt that way. But as soon as we started working with Dillon, we understood that our dog was actually amazing. Once we could successfully communicate our expectations, our dog was so much happier and we were able to get him to a point where we can fully trust him in practically any environment. Now we’re extremely proud of how well trained our dog is and of the amazing relationship we’re able to have with him. None of this would have been possible without Dillon’s unique approach.
We highly recommend Dillon to anyone and everyone!
