All Cane Corso Rescue dogs are spayed or neutered before being adopted unless there is a medical reason not to. Like many rescues & shelters across the nation, Cane Corso Rescue neuters or spays all dogs before it places a dog into its adoptive home. 60% of the dogs that are accepted into the rescue are already spayed or neutered by their previous owner or a shelter. Since we are a rescue that is incorporated in the State of Texas with Offices in Texas, we are required by law to sterilize (spay / neuter) all dogs or have the adopter sign an agreement stating they will have the dog neutered / spayed.
