Our Dogs

Our HouseWelcome to Mosier's Gentle Giants.  We are a family dedicated to raising healthy, happy, well-socialized Bullmastiff puppies that will make a great addition to your family.

My husband Mark, myself (Debbie), and our son Ryan share 10 acres on the edge of the small town of Sargent in central Nebraska with our beloved Bullmastiffs.  Our two grown daughters and grandchildren are here often.

Some of Our DogsDespite their large size, Bullmastiffs are active dogs outside but behave well in the house and are content to sleep comfortably at your feet.  Our dogs have a heated / air conditioned dog shed with a 50' x 110' shaded, grass covered area and a fenced 7 acre pasture where they run and walk daily, but they prefer to be in our family room with the family.

Our dogs are raised as part of our family, and after much research, continuous learning, and careful selection of our dogs from experienced breeders, we find we are ready to offer a litter of our own to selective, loving homes.

We currently have puppies available! See the puppy page for details.
