Working Dog Team

Our team of trained working dogs, ranging in age from 3 months to 7 years old, assist our trainers when we are working with our clients to improve their dogs’ behavior around other dogs. Some client dogs are fearful, some too excited, and because our working dogs each have different personalities and skills, we match the working dog to our client dog’s needs for training!
Each dog’s unique bio is below so you can get to know a bit about our amazing team of dogs!

Slash is our main working dog at Happy Tails! At 5 years old, Slash LOVES to work every day. He thrives on helping dogs of all ages, breeds, sizes, and backgrounds. Slash has an incredibly special gift to communicate with other dogs, understand what they need from him, and let the other dog know he is there to help! Outside of work, Slash is a fun, loving, sweet boy who enjoys play dates with his bestie Cooper, walks with his male human, and exploring his big backyard.
