Meet the breeder

I'm Mark O., the breeder behind Mountain Guard Cane Corso located in Glendora, CA. We specialize in breeding high-quality Cane Corso pups. Our program is founded upon love and passion for this magnificent breed! We love these dogs for their trainability, guardian temperament, stability, devotion, and calm demeanor.

Q. & A. with Mark

  • Why did you start breeding?

    Before being introduced to the Cane Corso, we were avid Rottweiler fans. Although we still appreciate Rottweilers, our appreciation for them was surpassed by the phenomenal Cane Corso. Our love for this breed and devotion to preserving our extraordinary bloodlines inspired the start of Mountain Guard. We have been fortunate to meet many amazing breeders, handlers, judges, and mentors along the way!
  • What makes your program special?

    Our Champion Cane Corso bloodlines come from nationally recognized breeders to ensure quality puppies. They have also passed all of their health clearances and are incredible representations of the breed standard. We are devoted to maintaining the unique qualities of the Cane Corso. It is such an honor to preserve the line of these incredible dogs all the while creating companionship for others!
  • Where do your breeding dogs live?

    They live in my home.
