Testimonials
My 3 month old Doberman puppy is almost done with the class and I couldn’t say better things about Mary and her training. I’ve had dogs pretty much my whole life so I honestly thought I wouldn’t learn much. But I wanted to go since owning a Doberman was a new experience for me. Mary has taught me so many new things. She gives clear directions and advice on how to work with your pup. I’ve been working with my Doberman at home and now understand how some of the little things I was doing could lead to bad habits and why. I would highly recommend Mary and her training classes.
– Client
Mary is the best dog trainer I’ve ever worked with (been a client since 2007). I love her approach and how she teaches “both ends of the leash.” 🙂 She is so intuitive with the dogs, and often picks up on some small queue and raises it as a teaching moment, helping her students understand and become better trainers, in turn. The dogs love her too, and we all came away smarter, thanks to Mary!
– Client
My family has been taking our dogs to Mary’s training classes for literally decades. She is the most knowledgeable dog trainer in the area (probably the state!). If you want a well behaved, trainable, and sociable puppy, I highly recommend her Puppy Kindergarten classes.
