Our 13 week old pup starts training classes this weekend. Recommendation from a friend and all looks very gentle and reward based which is good. The trainer has just sent an email though saying that any puppy biting or humping another dog/owner or trainer will be banned. I am now really, really nervous as our pup is the classic land shark at the moment. She seems to have no bite inhibition at all, just gets very, very excited when playing. We are going to get banned, aren't we?!
