These puppies are ACA and CKC registered. I don't think you can limit the registration of these two "registries".
ACA is American Canine Association -
American Canine Association and CKC is Continental Kennel Club -
Continental Kennel Club Puppy Registration and Free Litter Registration
AKC offers limited registries and the Canadian KC offers non-breeding registration. If you don't want these ACA/CKC puppies being bred you need to provide spay/neuter contracts
