I have Schatzi my GSD and Cudi my malamute. They get along, both are trained and socialized. When someone approaches the gate or the door Schatzi starts barking and I have no issue with that. My issue is when Cudi does it. I have noticed that every time he starts barking, howling, or sometimes growling and Schatzi gets near him he snaps at her and they get into a confrontation. It hasn't gotten to a point where they get into a fight, but Cudi has pushed it a bit and I am getting worried that I might get home one day and find them hurt because of it. Cudi only acts this way at home when someone is getting near the gate or our house. Never has he shown this type of behavior outside with people and/or dogs. Now my question is how can I prevent this from escalating. Nobody is home during the day. I have no issue with them barking when someone gets close to the house, I just want to find away to stop Cudi from snapping at Schatzi.
I don't know how to tackle this problem. When it happens and I am home I go outside and Schatzi runs towards me and Cudi snaps out of it. I just stand there and making him sit/stay until the person is gone. I don't know if I am doing it right. If you guys have any suggestion I would grateful.
