I'm Brent H., the breeder behind Blackberry Cabin Farms located in Ranger, TX. At Blackberry Cabin, we proudly raise three breeds of dogs that work and play on our farm: Miniature Australian Shepherd (Mini American Shepherds), English Mastiffs, and Yellow Labradors (white coats). All our dogs are purebred, and our family is deeply committed to breeding with the utmost care, prioritizing the nurturing of healthy and affectionate companions. The Labradors are beautiful, energetic, and particularly enjoy river and boat time. These sweethearts bring joy and excitement to our family outings. The goal for our English Mastiff program is to breed athletic, fit and happy mastiffs rather than focusing solely on size. Our Mastiffs love taking long walks on the farm and cooling off in the ponds. Our Mini Aussies are intelligent and the workhorses of the farm. They are always eager to assist with daily tasks, especially round up time.

About Josey
Incredibly perceptive and quick to learn, she masters new tasks with remarkable ease. Jose may very well be the most nurturing mother we've ever encountered—caring for her pups with the instinct of a seasoned expert. Beyond her maternal devotion, she’s an invaluable presence on the farm, always eager to lend a helping paw."

Never met a happier dog in all my decades - Not only is he a naturally joyful English Mastiff, he's even keeled, attentive, well-socialized from the get go, and a loyal canine extension. Much thanks and kudos to Brent and Shari for all their amazing work!

Brent and Shari were a pleasure to work with. They are very knowledgeable about the breed and the pups are beautiful. This is our 4th Mastiff and he's fitting right in with his big brother Shaggy.

Brent and Shari were a pleasure to work with! They answered all of our questions, provided pictures and videos of the puppies, helped us choose the puppy that would best fit our family, and had an organized care package that included our puppy’s documentation at pickup. Their puppies are clearly well cared for and loved. We fell instantly in love with our pup! He came to us happy, healthy, well-socialized, and so incredibly cute! We hope Blackberry Cabin Farms is still breeding mastiffs in a couple of years when we’re ready to add to our family again!
