All dogs have the potential to develop genetic health problems, just as all people have the potential to inherit disease. Run from any breeder who does not offer a health guarantee on puppies, who tells you that the breed has no known problems, or isolates puppies from the main part of the household for health reasons. A reputable breeder will be honest and open about health problems in the breed and the regularity with which they occur in her lines. Some of the health conditions that have been seen in the Cane Corso are hip dysplasia, eye problems such as entropion or ectropion, demodectic mange, and a tendency toward gastric torsion. Although hip dysplasia can be hereditary, it is often caused by their new owners over exerting their puppy and/or allowing it to use its back end (climbing hills, jumping on furniture, climbing stairs, running on pavement) before it has completely grown. When a growing dog uses its hind end (like climbing hills, jumping on furniture) before it is completely grown, it stretches out it muscles, tendons and ligaments. If the muscles, tendons and ligaments are stretched out, even just a little, the ball joint will be able to move in the hip socket in a way it is not supposed to and this will wear away bone, which over time causes HIP DYSPLASIA. So don’t over exert your puppy while it is growing, so the muscles, tendons and ligaments don’t stretch and will hold the femur tightly in the hip socket when it is fully mature. If you have a large breed dog, wait until it is around 1 1/2 years old and smaller breeds should be at least 1 years old, before letting them use their back end to climb and such to protect them from this very painful condition.
