Chloe just attacked my brother. Mom said everyone was sitting in the living room watching a movie and he was petting her. She just up and tried to maul his arm. Had he not been wearing layers of clothes he would have been seriously injured. As it was, he was able to pin her down until she calmed down and got away with only a few bruises. I wasn't there so I don't know what happened exactly, but mom said she had never seen her like this before. She normally nips or snaps, but mom said this was a full out attack. I can't have my family care for a dog that tries to attack then when they're just sitting there. I can't risk that happening to someone else. She does it without warning, for no reason. She will illicit attention and then turn and bite you when you pet her. This has been getting worse and I always said if she started biting and not just nipping I would have to do something. That just happened. Now my heart's dropped out of my chest and I don't know what to do. Do I try to have her at my apartment? She'll stress out. She'll bark. She'll attack the three munchkins if they walk by her when she's in the wrong mood. She'll be an anxious mess. I'll have to constantly worry about how she and Mike interact. Prozac didn't help. Behavior modification has only got us so far, and I can't modify her just spontaneously aggressing because there is no trigger. Or do I say this is it, throw in the towel, and let her go? I don't know what to do.
