-they specialize in breeding only one or two breeds of dogs -they interview you extensively to be sure their puppies are going to the best homes -they offer a return guarantee should you have health or behavior issues -they allow you to meet at least one of the puppies’ parents Keep in mind, just because the breeder says the dogs are AKC or ACA, it does not mean the breeder is reputable.By the way, the designation of ACA (American Canine Association) was created by pet store owners and Amish breeders to bypass the requirements of the AKC.An AKC or ACA title does not guarantee anything.
