If you can't find homes for the puppies, you keep them intill they are sold. My aunt breeds Great Danes and she is CKC registered. And she is also a vet. My aunt knows what she is doing and is willing to keep the pups intill they find proper homes. Most breeders that are backyard breeders, turn the pups loose, get them put to sleep, or give the to shelters. SO you do have to be prepared because it's lots of money and work.
