Hi, I live in the UK and we have had Teddy our yorkie pup for nearly 4 weeks now. He's a very good puppy. How can I tell if he is a true yorkie? He isn't a pedigree so I suppose that says a lot, although we saw mum and dad who were yorkies. I have hopefully posted a picture, perhaps you people could tell me? He is now 13 weeks old in this picture
