I am curious. Is it possible for a breeder to offer both AKC and ContKC on the same dog? If I am NOT going to breed or show the dog it does not seem to make sense to spend the extra money to get AKC. Also, at what age is it safe to get a yorkie puppy? I am getting conflicting information.
Yes dogs can be dual registered with multiple registries, though of course it costs money for each registration. Personally I'd never get a ContKC registered dog or even consider getting a dog from someone who breeds ContKC registered dogs. I consider them to be a shady for-profit registry that's not interested in anything other than lining their pockets with the registration money.
The AKC is a far more respectible (though imperfect, no registry's perfect) not-for-profit registry. At least the AKC uses the money to fund canine health research, and offers hundreds, if not thousands, of performance and conformation events for dog lovers and enthusists like yourself to participate in. They also work harder to maintain the integrity of their pedigree and stud books (the ContKC will register a dog as a purebred based on a picture and nothing else, so any mixed breed that strongly resembles a purebred can be registered wtih them).
If you don't plan on showing your dog or breeding her, why pay the ContKC to register her at all? I'd rather pay the extra $5-10 to get my dogs registered with the AKC, just because I feel the papers have more value to them due to the history and respectability of the AKC. Plus, if I ever wanted to do something like Rally Novice or something like that with my dog the AKC actually *has* events like that I could do. ContKC has squat.
Is the breeder doing any health testing on the puppy's parents, in the form of CERF for eyes, or OFA certification for patellas? With a small dog like a yorkie, most good breeders arent' going to let them leave home before 12 weeks of age, to make sure they are in good health and not at risk of hypoglycemia due to their ultra small size. Run away from any breeder who is trying to send them home before they are 8 weeks old (really you should do that with every breed, not just Yorkies)
Never trust a tall dwarf... he's lying about something.
