My male is AKC regestered and my female is ACA regesterd. My female has had 3 litter of puppies and I have regestered them all with the ACA. They are purebreed yorkies and to be honest I didnt realize it made a difference where they were regestered, not that it has mattered to anyone that has bought one of my puppies. They are in good health, I make sure they get their shots and are checked by my vet before I ever sell any of them. They are adorable and by the way one is a chocolate which I have learned from this site is not considered acceptable by some breeders.
