I took Molly in for a 2nd opinion this morning and the vet said that there is no reason to extract any of her teeth as her bite is fine. Since the bottom jaw grows slowly, when the adult teeth finally come through it'll correct itself in the process. He said at only 13 weeks of age it's too early to see any problems arising, but mentioned again her bite is fine. After all that he didn't even charge me for a check-up. So when Molly is due for her 4 month shot at the end of January I'll be taking her back there. I have already canceled her appointment with my previous vet.
Thanks for all your posts.
