I was just reading your post and my two boys saw Remmie's picture and both went "Awww, he's so cute". He looks all yorkie to me and most yorkies are on the long side, they're now just breeding them to make them shorter. I don't think I'd necessarily use him for breeding though. His ears don't look like they stand all the time.
I know how it is to not get what you wanted though. I bought a long haired chihuahua years ago. I paid a lot for what I wanted(a small long haired dog). She turned out to be about 12-15 pounds
She lived 15 years and I loved her but I always wished she was that tiny long haired dog I saw in magazines.
