I'm Kate S., the breeder behind Mountain Meadow Ranch located in Huson, MT. My dogs are part of the family first and foremost and live in my home. I breed for quality, conformation, and disposition. While showing is not my main focus, I take pride in the recognition I get for conformationally correct, quality dogs! I have many years of experience with these breeds, so I am happy to tell you more about what life with a Mastiff is like and how they will not only enhance your daily life, but exceed your expectations!
