I think my 5 mo. old pup has a pretty serious overbite. I'm really concerned, but I'm not sure what course of action to take. It looks like he's cutting the roof of his mouth. I don't know how much his lower jaw will grow etc, and my vet seemed pretty uninformed.
I have a photo but it's just a jpeg and I don't know how to attach it :-/ He has about a quarter inch gap between his lower and upper jaw.
