I am in need of some advice! We have had Harry now for about 8 months. He will be 2 in June. We recently adopted Lady, 2 yo female fawn boxer who is just adorable. They get along like they have known each other their whole lives. The rescue informed us that they might have some problems with one another because that usually happens for the first couple of weeks, in regards to sharing toys and mainly Harry being protective of us. But they have yet to get in an argument over anything! Harry has had some dominance issues in the past. He is neutered but still seems to show that male dominance side with some dogs, this is before we got Lady. Now that we have Lady, when we go for walks, if there is another dog the hair on Harry's back raises up and he growls like he is trying to protect both me and her. Like I said earlier, this would happen before we got Lady occasionally but now it seems that he is trying to be way to overprotective. Does anyone have any suggestions? I just hate for my Harry to look like the mean dog when I know that he is so sweet. It is almost like Harry and Lady have communicated and he knows what kind of past Lady had and he never wants to let her get hurt again. I know this might sound crazy but they have developed a really close bond but I fear that it has made Harry a bit more aggressive.
