I'd be willing to bet he is full yorkie, just larger. Just like people, yorkshire terriers come in all sizes. I had a long haired chihuahua that ended up being about 15 pounds and I know she was 100% chihuahua. There are quite a few 10+ pound yorkies on here and I know of two in my small town. I think in any breed you can find some alot bigger than the norm and some alot smaller.
Ears standing doesn't really even have to do with size or purebred. Carmen Electra has a very very tiny yorkie(who you know is full blooded) yet has ears that lay down. While your boy is probably not quite what you pictured size wise, I'd bet he has the great personality yorkies tend to have. |
