Looking at Gina, neither I, nor anyone else has ever noticed anything wrong with the proportion of her lower and upper jaw. I have started her on some basic manwork and the trainer has not been able to get a good holding bite from her, even though she is very enthusiastic to play with the sack he is using. We looked into her mouth and were horrified to find that the top incisor teeth are actually situated behind the lower canine teeth when the mouth is closed. It seems to me that this is the problem. I have no great expectatuions with the manwork and am merely doing it because Gina seems so enthusiastic and seems to enjoy it so much.... so the holding bite is no great train wreck for me. I am concerned that the amount of undershot (about 1 inch) might cause her problems in eating later and I was wondering if anyone else has experienced this problem. I will try and take some photographs of her mouth.
