PROBLEM DOGS ARE OUR SPECIALTY

Our team has great success with obedience work and aggressive dog rehabilitation. Because we know how to train dogs to react appropriately in situations involving protection, we understand how to break aggressive habits in a family pet. We are able to fix—or prevent—challenging problems that other trainers won’t touch. We are eclectic in our approach; we use whatever tools are necessary to correct the behavior, including positive reinforcement and corrections when appropriate.

We start every pet/owner/trainer relationship with the goal of correcting the issues that are preventing you from enjoying your pet. Alot of our work involves teaching you, the dog owner, how to apply the techniques that get results.

As expert dog behaviorists, we focus on identifying and modifying the root causes using science-based approaches and canine psychology.

OUR SUCCESS STORIES

  • Amanda Margolis

    My experience with Ancillary K9 has been nothing short of amazing. Shortly after adoption, my dog Yeti showed fear and sometimes aggression towards other dogs. We tried group training classes but it was a disaster. I was really at a loss and knew I had to do more. I reached out to Ancillary K9 with Yeti's story and in that initial call, I was ready to get Yeti started ASAP. Prior to our first session, I felt Yeti understood the "basics" of obedience. I also felt Yeti's challenges were more social than anything so I wasn't sure how more "training" would really help us. I NEVER would have guessed how much this course would've changed both of our lives. In the first session, Dion was extremely invested in understanding what brought us to the course and what challenges we were facing. Dion was not interested in applying blanket methods or focuses of the course - it was catered to both Yeti and myself. This course has given both Yeti and myself so much more confidence. We laid pivotal building blocks and set goals. I immediately saw a change in both of us - more confidence in knowing how to react to a situation. Yeti has grown so much because of this course, all thanks to Dion!!
