can anyone tell me how old my pup will be before he goes undershot? he is 19 weeks now and when you look at him his front teeth seems to be overshot but the side teeth are undershot.

you normally find the bottom jaw is the last to stop growing,and he definetly has'nt finished at 19 week's,i myself would like to see the bottom jaw undershot by now,but all you can do is wait and see ,you normally find the bottom jaw is wider through out so this will give you this impression,at this point in time all you can do is wait and see what time bring's ,did you buy your pup to show or just as a family pet,
