That's not very nice..."non-reputable" hmmmm not everyone is YTCA members...or likes their standards...
just because someone breeds off colored or non show or fault colored Yorkies doesn't make them non-reputable by any means...things like
breeding practices, care of their dogs, placement concerns etc make them reputable and non-reputable in my opinion. Of course so does their sale practices.
Given many off (or fault) colored Yorkies are bred by greeders, unfortunately some people only use color as the breeding quality and that is dangerous. Most people getting a Yorkie are not looking for a show quality Yorkie, they are looking for a pet. But still the generalization in saying someone is non-reputable just because they don't breeder per YTCA standards doesn't make them such...I have a Parti and think they are the most wonderful...weather the YTCA agrees or not...
finally the AKC does that's good enough for me. My Elvis is a black and silver Parti on his papers
Yorkshire Terrier -
Above is the Parti Yorkie Club, they have their own shows for Partis and can give out information on other fault colored Yorkies to people.
There is also the Biewer Club, personally I think its silly
they are all Yorkies.
