Breeders
Guide Dogs breeds most of the dogs used in its program. Breeders are exchanged and loaned between programs to ensure a sufficiently wide gene pool. During formal training, dogs may be selected as breeding stock dogs. Most breeders live in the homes of volunteer breeding stock custodians within a 50-mile radius of the California campus. A slightly longer distance from the campus is allowed for breeders living with custodians who were also the dog's puppy raisers.
