I always assumed that Roxie's lunging, barking, screaming at other dogs while she was on her leash meant that she was dog aggressive. Well, my bf took her to visit his family for a couple weeks where she met two female dogs, one of which wasn't spayed yet, and she got along with them just fine when she was let off her leash to see them. She had a great time playing with them. Is her barking and lunging on a leash just excitement then and not really aggression?
