Cujo woke me up to go to the bathroom, and now I can't go back to sleep, so I came to YorkieTalk, lol.
Anyway, my take on the teacup debate: I think it's misleading b/c many people aren't thinking of teacup as an adjective, but as "teacup yorkie" as a noun, if that makes sense. They think it is actually classified as a different dog than the standard yorkshire terrier. I see it as a red flag when in a listing b/c it makes me think they either haven't done their research on this breed, and thus, have absolutely no business breeding them, or they are intentionally misleading people.
I mean, really, you can't know for sure how big a puppy is going to get. You can make an educated guess based on parents and grandparents, but you can't know for sure that one won't turn out bigger or smaller than one would have thought. So, I think selling puppies as "teacup yorkies" is misleading, seeing as that isn't an actual breed and you aren't 100% certain how big the dog will get.
Cujo is 4 lbs (I just describe him as kind of a runt), and when people ask me if he's a teacup, I just say, no, that there isn't really a such thing as a teacup yorkie that some just get bigger than others. I don't go into a big speech or anything about it, unless the person says, "Oh, really?" and and asks about it. And I've really been surprised at the number of people who do ask and want to be educated, b/c they had no idea and actually thought there were "teacup yorkies" and "standard yorkies."
Anyway, just my $.02 on the matter. Cujo's waiting to be my snugglebug again, so I'm gonna try to get back to sleep.
