I would appreciate other's experiences with overbites.

I have a litter of 4 1/2 week old puppies and one of the little boys has an overbite about 2 match sticks wide. The litter is from a bitch who had two overbites in her last litter and was bred to a different sire this time. (I will not be breeding her again now)

My question is does an overbite at 4 1/2 weeks usually progress and get worse or turn into parrot mouth or does it usually improve? I have never noticed an overbite this early before.

A long time friend and mentor once old me early on and I have found it to be fairly true, 1/8 inch could likely correct but over that and well.....good luck.
