The Perfect


We provide Force Free and Certified Dog Training as well as Animal Assisted Therapy to fit your lifestyle and goals. We provide group classes, private training or a mix of both. In your home, location of your choice, or in our safe class setting, we've got you covered!

Private training accommodates your busy schedule and takes place in your home and neighbourhood. Whether you have a puppy, an older dog, or several dogs, private dog training is a fast, effective and proactive approach.


You and your dog will love our positive, rewards-based instruction.

Group Classes are a fantastic learning tool for dogs and owners alike. They offer an opportunity for dogs to become comfortable with other dogs, individuals and environments while learning a variety of skills ranging from trick training, scent detection or agility to certifications like Canine Good Citizen. 

Group classes vary by season and interest. 

Ruff n’ Tumble Kindergarten provides puppies with a strong foundation of learning with all of the major commands and important socialization to help them grow into confident, well behaved dogs.

For a more advanced option, choose VIPuppy for an in class experience followed by a private in home session.

We adopted our mixed breed pup Queso in February 2017 and secured Diamond in the Ruff for private training shortly after. Queso was a Mexican stray, and although she has a heart of gold we needed some support to help her adjust to her new life. Colleen was fantastic in our private sessions and helped us to learn about ways to ease her anxiety and fears. She encouraged us to attend the Canine Good Citizen classes, which we really didn't think would be a fit for Queso. To our surprise she flourished and passed the testing! We are proud of our little mutt, and we wouldn't have been able to do without Diamond in the Ruff.
