AKC assures the consumer the breed is a purebred where as CKC and ACA doesnt monitor the past of their reg'd dogs.
The problem with buying a NON AKC dog is only assuring you that your dog is a purebred. The other reg'ing agencies will acccept a picture of a dog as gospel. That as a breeder is a scary prospect because there are so many dishonest breeders and just as many uneducated buyers that get taken advantage of. Its refreshing to see there are many people on this forum that are educated buyers because they are lovers of the breed but many buy on impulse and if someone calls it a yorkie its a yorkie
even if it is 3/4's yorkie and a 1/4 party mix (rover).
Buying AKC assures and protects the buyer "that puppy in the window" is a real Yorkie
where as the other reg'ing agencies hope that the reg'ing party submitting the documents are true.
Buying AKC in most cases is a more expensive venture but at least you know when your puppy purchase is all said and done ITS A YORKIE!
