I don't own a chi. But remember, chi's shed, yorkies don't. and even though chi's are small, I have heard chi owners complain about the teeny tiny shedded hairs that are so hard to get up. That's just one con, but the only one I know of. Personally, I like yorkies. I like their personalities better and I think they are so much cuter although a wet yorkies resembles a chi IMO. But the hair just really does it for me. Good Luck in your search. Sorry, we are biased here
