She's a very pretty dog. Well, when we first got Mac we had another male dog that was 8 years old and smaller. He was aggressive towards him, and we had to put Mac in a pen and just take him out to walk him. We would put him on one leash and the other dog on another leash and if one started to growl we would take him away. He was never aggressive towards female dogs. I think they're just territorial and protective. As he got older they could be together more, and eventually the older male dog died. We haven't kept Mac penned up since then, and we just have one other dog(small female). Now he's only food aggressive towards other animals. Maybe Josie will mellow out as she gets older. You may have to try separating them. How old is Zuzu?
