After reading your post again I'm really disappointed that you allowed this to happen a second and third time. You are not taking this seriously enough. You simply MUST make your facilities where you keep your pack safe for them. GATE. CRATE. ROTATE. Line on the aggressor dog even when you're right there, so you can keep everyone safe. Brittany, once this has happened (to this degree of seriousness) you can never be comfortable that it won't happen again, I will repeat, you must control the environment.
