Welcome to YT!!!!' Milo is CUUUUTE!!! I would have thought he was all yorkie looking at his pics if you hadn't said anything lol. I think maltese are usually around the same weight as yorkies , but of course some are "out of standard" weight wise and there are bigger maltese like there are bigger yorkies. I have no info regarding the overbite but this should bump you in the threads. I'm sure someone will come along who has answers
