I joined here because of my yorkie puppy Clark, but I thought I'd share something funny.
I have another dog, Maple, that we've always termed a 'mystery' dog. She was tiny when we got her at 12 weeks. She's currently 3.8 lbs at nearly 2 years. We were told that she was a poodle/maltese, but I knew there was another breed in there, as she had erect ears and a stiffer coat than a poodle or maltese (I've had both of those before). She's mostly all black with a bit of white on her chest and paws. Her brother was basically yorkie colors, with a poodle/maltese coat and floppy ears. So I thought she might have some yorkie in her somewhere, but most vets told me they thought she was more chihuahua or pomeranian than anything else.
I noticed once we got Clark, though, that Maple and him were a lot alike. Same fun loving personality, same playfulness, same ears, eyes and nose. I kept thinking maybe there was a LITTLE bit of yorkie in her, somewhere.
Anyway it was driving me crazy so I got a DNA test done on her. And the results are: less than 30% poodle/maltese - the rest is all yorkie! I was thinking there was a little bit of yorkie in her and here the results say over 70% yorkie! Too funny. Now I have 2!
Just wanted to share.
