Recently Jazz has started to become more agressive to other dogs and I'm worried about it. At home Jazz is an angel and never gets aggressive with Dixie, the two of them can eat and drink from the same bowl and they always share the couch or a cushion with no fuss. She is never agressive to people either, quite the opposite as she loves people. However at school or at the dog run Jazz takes on a different role that I don't like much. She is bossy and growls or snaps at other dogs that she doesn't know or like. I tried telling her off or walking away from her to let her know that I'm not pleased with her but it doesn't work. Dog Inc doen't accept aggressive dogs and I'm so worried that if she continues on this path she won't be able to go there anymore. Any advice as to how I can handle this problem would be greatly appreciated.
