Hello. I am new to the site also. I will post pics soon. Once my computer at home is up and running again.
I was going to name our newest dog Abby if it were a girl, but we ended up with a boy, so we went with Jaxin. He's a hairless chinese crested. Our yorkie is a "teacup" at 3.3 pounds. He will be 1 year old on Nov 4th. His name is Oliver, and he's just adorable. He also has a little overbite

, but I totally love it.
Every once in a while his tiny, little tongue will peek out of his mouth a little bit when he is really relaxed, or sleeping.

It is the cutest thing. I am pretty sure that it is due to his overbite. His adult teeth are in now. He just had all his baby teeth pulled, because the adults grew in, and the babies never fell out, but they look perfect now. His overbite has not changed at all, but it really isn't noticeable to anyone but us. I don't see how it would change with the growth of adult teeth, since an overbite it usually due to a smaller, or futher back set, lower jaw (I think).
I wouldn't worry about it anyways. It just adds character.
