Hi all. We have six dogs which includes our Basset, an American Bulldog, and 4 mixed breed. The mix breeds include a mom, 2 of her sons, and her boyfriend. At first, our Basset would fight with the mom, so we separated them both, but recently, Abby, our Basset seems to want to fight everyone else. She would get so upset, growl, and attack. The other night, I was wiping her face, one of the boys who she is really close to (they play, sleet, etc. together), came by her and she barked and attacked him. He doesn't fight back with her but lets her have her moment. I felt bad because she was biting on him and of course he defended himself. My husband broke up the fight and slammed the hamper down onto the floor which scared Abby and got her to stop growling. Tonight, when she was on the bed in the living room, our American Bulldog got closed to the bed and she did her usual growl. We told her "no Abby, be nice," and she would stop. But then she would keep on. My husband went up to her to put her face down and she growl and barked at him. We punished her by putting her in her room (laundry room) and closed the door which we normally don't do. Everytime she plays with the other dogs outside and gets hurt in some kind of way, she would growl bark and attack the other dogs. She is not loose but is on a long chain which she is very used to. She has not been like this all the time. I'm not sure what to do? I haven't talked to the Vet, yet, and not sure why she is being like this. She has not always been like this. She has always been an inside dog and gets a lot of freedom. We say we've just spoiled her, but when she starts trying to attack us, it's just not right. Any help would be appreciated. Thank you.
