Well, this sounds like what I am going through, Alphie is my rescue dog and I have 2-other males, Jack, yorkie. Oscar schnauzer. They are really getting into fights. It starts out when my husband comes home and they are excited about seeing him. If I don't go and hide one of them in the other room they go at it. (all you see is hair.) I have gotten in the way ONE time Not anymore. My husband just holds out his steel boot and Alphie bites it instead of us.
Alphie is getting fixed tomorrow they can't guarantee this will help but they said it might. (wow what a comfort) We have told him No, and they seem to calm down. But Alphie stalks him all day.
I am wondering if I made a mistake in taking him.
