I agree with heinz. If your dog isn't already registered, that means he came from backyard breeders. Which means there's a very very small chance you can actually show him. And because your dog came from backyard breeders, you don't know anything about his lines. He could have terrible diseases in his blood lines that you'd be passing on to the pups. Have you done his OFA or Penhipp? CERF? BAER?
