Thanks for responding. Yes, my little guy is neutered. He is a singleton, which I have been told by animal behaviorists that that is a lot of the problem. Being the only pup in the litter, he did not have to fight for Mom's affection, food, or learn the proper socialization of his litter mates (i.e. playing, fighting, or understanding the pecking order). He is much more territorial at home. I agree with what Princess Diana said and have read that same information elsewhere. I would definitely introduce them somewhere other than our home. We want another so badly, and to have his little sister would be a charm if it all works out!! Thanks for your time and comment! Happy Thanksgiving! Sincerely, Barb |
