Tucker and Butler do not get along. So everyone goes to their crate for food. Tucker is presently wearing a cone because he has started obsessively licking one paw. He is sulking because he doesn't like the cone so he doesn't eat. Last night, Butler and Redford were out of their crates and Tucker was picking at his food. Butler was about 8 feet from Tucker's crate and Tucker started growling at him. Whenever he would growl, I told him "no" in a low volume deep voice. We also had a stare down until he broke his gaze. Then Tucker's food was taken away (he had already had 15 minutes to eat).
I am concerned because Tucker has been very aggressive to Butler and once to Redford when he thought Redford was getting too close to the bag of chewies on the coffee table (Redford was just shifting positions while chewing a bone). The distance part bothers me as well as the fact we haven't had any problems recently.
I worked with a trainer for awhile and she could get Tucker and Redford walking next to each other. But she's not "Mom", she's the no-nonsense lady that comes to the house weekly. There's a different dynamic between the dogs and me.
