I'm Matthew J., the breeder behind JSM Corsos located in Hesperia, CA. We care deeply about our dogs and have built that love and respect for the breed into every aspect of our program. Our goal is to ensure every dog that comes from our program is set up to live a happy and healthy life and is prepared for its future role when it leaves our care. We provide each of our pups with lots of socialization and love, and we are dedicated to maintaining responsible breeding policies. As soon as the pups are finished with their necessary shots, they are outside working along side of me. They are taught, "stay, wait, go to bed, no." We do not encourage high prey drive. Therefore, from day one we introduce the pups to the farm animals. Donkeys, cows, sheep, goats, chickens, rabbits and the barn cat. We are not allowed to eat, chase or harass other family members. In fact, we try and have successfully dulled the prey drive in our program. We breed for family, protection, livestock work and personality. Personality is of the utmost importance in this Kennel. There is not one single dog on this property that I do not trust with my three daughters. All of my dogs hangout with me all day. We clean kennels together, do the dishes, mop, feed and most importantly run and play. You'll notice with my dogs that they know how to move, jump, run and have common sense. They are calm, happy and so affectionate. They really are my best friends! We produce proven Champions!
