Hi...  Welcome to Sleeping Giant Cane Corsos! After a couple of years of researching Rare Breeds, I purchased my first Cane Corso in 1995. Although the Corso may not be for everyone, I found them to be smart, athletic, and eager to please! Since then, we've found that ours are great family dogs; they love kids and other animals. The Cane Corso is a dominant breed that requires a lot of socialization and training as a puppy. Given that, they will be loyal, loving additions to your family.

Sleeping Giant is not a "kennel". We are small hobby breeders; in fact, all of our dogs live in our home. We do have outdoor facilities where our dogs can enjoy nice weather during the day. We both possess past experience with larger, dominant breeds. Keith had Dogue de Bordeaux (French Mastiff) before his first Corso, and Kathy was born into a family who bred German Shepherds. Her parents were President and Vice President of a large GSD club for over 15 years, and Kathy was conformation showing and obedience training Shepherds at a very young age.

Here at Sleeping Giant Cane Corso we breed only OFA, Pennhip, or FCI HD certified dogs with no degenerative joint disease (DJD) present. Our goal is to produce healthy, sound dogs with great temperament and type. We usually only breed once a year because quality is important to us. We never breed our females on back to back heat cycles, so they always have a full year off between litters. We do not breed just to sell puppies; we both have full time jobs to support our household. We breed to improve upon our lines, striving to produce the perfect Corso, both in temperament and type. We invest a lot of time and money in this quest, and we were the first breeders to import frozen semen from Italy. We have also imported dogs from Italy, and we breed to meet both the AKC and FCI standards.

We take rearing a litter of puppies very seriously, and spend an enormous amount of time observing, handling, and playing with them. We employ the Bio Sensor, or Super Dog method on our pups between 3-16 days of age, which we feel gives them a superior advantage for life. Then, beginning at two weeks of age, our puppies are each given at least 30 minutes of individual attention daily. We have found that this time away from their littermates increases their confidence and begins teaching them social skills. Our puppies are also socialized with adult dogs and with children before they leave our home. Many a puppy has gone to day care and school with our daughter for "show and tell", which seems to help them adjust easily to families with children. All of our puppies are vet checked, vaccinated, micro-chipped and given a clean bill of health before they are sold. We give a written health guarantee with our puppies, and offer a lifetime of "puppy support" after they go to their new homes.


We are very selective about the homes our puppies go to, and want to insure that they are given enough love and attention as well as training and socialization. The Cane Corso is a breed that requires a lot of human interaction, so they can be quite time consuming. If you don't feel that you have the time to invest, this may not be the breed for you. We strongly suggest Puppy Kindergarten and Basic Obedience as a minimum amount of training. The Corso breed is extremely intelligent, it learns quickly, and seems to excel in obedience or any other type of training. They are active and athletic mastiffs, but given the proper daily exercise, make a good couch potato at night.

Please go to the links page if you need more information about the breed. You can read about the breed's history on the CCAA website.  We have been very active in the CCAA breed club for over 20 years; both serving as board members and committee members. Kathy is a CCAA approved breed mentor for AKC judges learning about the breed. We also founded the breed club rescue which evolved into the only National Rescue for the breed and feel very strongly about helping other, less fortunate, Corsos.

Inquiries and visitors are always welcome. Please feel free to contact us via email or telephone. We'll always be happy to take your call, answer your questions and have you come over to meet our dogs. Please note that many of the dogs on our website, although produced by us, live in their own, co-own homes.
