Why Behavioral Training Matters

Investing in behavioral training for your dog is one of the best investments your family can make. Addressing behavior issues in your dog is crucial because the longer these behaviors persist, the more ingrained and challenging they become to correct. Immediate intervention prevents these problems from escalating and sets the foundation for a lifetime of good habits. Behavioral training transforms issues like anxiety, aggression, and excessive barking into manageable and positive behaviors, leading to a happier, healthier, and more balanced pet. A well-behaved dog enhances the quality of life for your entire family, creating a safer and more harmonious home environment. Our expert trainers use techniques to ensure lasting results, making this a worthwhile commitment that will bring joy and peace to your household for years to come.

What people say about our Behavioral Dog Training Program

Dion is great.

He speaks in a way to get his point across with humor and common sense. He put me at ease from the start. I went at the training thinking not much more could be done for my female (one and a half year old Catahoula leopard dog). I am her third rescue as she is quite the handful. I know now why she was let go. She can jump a six foot chain link fence and run through the neighborhood like it's hers. She barks aggressively at other dogs, cats, birds, squirrels, thinks she's queen. After five sessions she has calmed down enough. I can hardly believe she was that wild girl a few months earlier. Simple commands that she would not do she now does automatically. It has been a short while with Dion and my girl has changed so much as I am so happy with Ancillary K9 I would highly recommend them to anyone.

“Dion is an incredible dog trainer!

The quality of our lives improved dramatically as a result of his teachings; and the outcomes? Simply Amazing!!! I moved to Denver from San Francisco to reunite with my ex-wife and inherited her two dogs. Their poor behavior was so disruptive that I questioned whether I could actually reconcile our relationship. My ex-wife tried several dogs trainers with no noticeable results. Feeling  hopeless; she just gave up. I was so desperate to help, I began to search for high quality dog trainers. After careful consideration I chose Ancillary K9, reading all the rave reviews gave me a sense that this was likely a good choice. I soon realized, that this was a GREAT choice with “jaw-dropping” results! By the end of 6 weeks they were blowing our minds!  Dion, has Mastered his craft, with skill and expertise. He helped me connect with these wonderful animals….AND let’s face it….Dion saved our marriage!”
