I just wanted to say that even though the post I read about 15 week old Mini Schnauzers biting when grooming etc. was dated 2003 it has helped me feel so much better with my litter-mate Mini's (one of which does exactly that and the other is laid back and calm) Thank you to those of you who have experienced the same and survived. Yes, as mad as it seems I have had litter mate sisters before but a different breed. Thanks again.
