Never had a J.R. but now I do. I've noticed, he's tiny, about 13 lbs. and shorter than our chi, BUT...he has the MOST teeth I've seen! He looks like a gar, or a gator when he's playing! The craziest part is, ok...let me see if I can explain this...he has a "typical" dog set of teeth, until you get to the fangs, then it looks like someone took ANOTHER whole set of dentures and stuck them in his mouth to extend his nose length!! (Make sense?) It's like he has another set of full dentures expanded from where his original ones stopped.
As I've said, I've never had a J.R. nor have I spent much time around them, or at least not enough to really look at their teeth....sooo, is this normal??
thanks
