Why do we believe our training methods are better?

Our trainers are members of the Association of Professional Dog Trainers. The professional training team at Holiday House Pet Resort & Training Center uses positive reinforcement methods for lasting results. Through the 3 “P”s — practice, persistence and patience —most any dog can learn using positive reinforcement.

Clear communication fosters confidence and creates a positive relationship. Teaching basic obedience establishes a language your dog can understand and sets expectations for good behavior.

No two dogs are the same. To achieve effective training and long-term success, the dog as a whole must be taken into consideration. Breed characteristics, personality, and overall energy level are evaluated in order to tailor a program that will connect with your dog. For example, herding breeds may have a different response to learning certain commands. Puppies may need extra time to learn so breaking down the process into easier steps is helpful.

A training program should be designed to fit the dog. It’s not as simple as giving a tasty treat when the dog does something good. Training should be physically and mentally engaging for the dog. Giving the dog the ability to think and problem solve are key elements to effective learning.

Positive reinforcement training is about teamwork and clear, consistent communication.
