Our Yorkie is almost 9 months old & I think that recently I am seeing an over-bite with her teeth. Can the vets do anything about that? I think that I have read that can be a bad thing & I am wondering how & why that happens? I don't seem to see it all the time. Sometimes it looks more noticeable then other times. If anyone out there knows any thing about this sort of thing I sure would appreciate hearing from you.
