Hi there. Welcome to YT!
My Tinkerbelle is a Yorkiepoo - mother was a Yorkie and father was a poodle. Tink is 19 months old and is all ebony black with a little auburn around her mouth a two silver hairs on her chest.
The two white hairs were there when I got her at 9 weeks and the auburn grew in late last summer.
She is what we here on YT call a "Tea Pot" because she weighs more than the accepted yorkie standard of 7 lbs. We made that name up because there is really no such thing, just as there is no such thing as a teacup dog. Tink weighs 10 lbs. 2 oz. and I love every bit of her.
She has the temperament of a Yorkie and the coloring of her poodle dad. I've never had such a stubborn dog. Her ears are shaped like a yorkie's and try to stand up but they are too thin - like a poodle's - so they can't stay up.
There are other Yorkiepoos on YT. Slade for one. And others that I can't remember right now. I hope one of them will see this post and offer more information.
Good luck with your little baby!
