Gabby is about 14 weeks and her hair has some curl to it! But I know that she is purebred, so I agree with higgins mom, just give it some time. He looks purebred to me too. I have a shipoo and she is awesome, but I know what you mean about paying a purebred price, people should give you what you pay for. It seems that the yorkiepoos that I have seen have VERY curly hair and are not at all the full yorkie colors, and most of the time their ears don't stand as well, and their noses are longer. As they get older I think that you will definitely be able to tell. At
www.mixedbreedpups.com you can see pics of all types of mixed breed puppies and they have adult pics as well. I hope that all of this rambling helped. Oh and look at the price of these puppies too.
