Sarah - 243618 Port Charlotte, FL 4/18/2013 10:39:40 AM Kimberly: It sounds like you have a leader of the pack in your pack and your parents have a leader in their pack. So, the two leaders are trying to work out who is going to be leader of the together pack that has been created. I'm sorry on not really an expert on the topic, but have you tried to introduce your pets from a distance? Food rewards? Have you tried to introduce on different territory like a dog park or some place where the dogs wouldn't be territorial and protective? We have two dogs and for the most part they get along. Our female however, is very unsociable with other dogs, especially if our male is close by. Neither one of them are fixed/spayed. Be patient and consistent with your efforts. I'm sure some kind of solution will present itself and the problem with get remedied. Don't loose hope.
