My 10 month old puppy barks at everyone she doesn’t know. She is okay with me, my mother, mother in law and my husband, for the most part, but she barks at everyone who comes near her. Even if my husband comes to bed after we do, she’ll bark at him like she doesn’t know who he is. She’s been barking at my sister in law and her boyfriend even though she’ll sleep with them at night and nap on them during the day and she seems to be okay with them when they are sitting. We recently moved into a new place that is much bigger than our old one and we have an extra person living with us. Just before we moved she was spayed. She was fine for the first month or so of us living her but then all of a sudden she started barking at any noise in the hallway, she never did this in the old place even though there were more noises. Then she started barking at people in the hallway, the elevator and on the street even though she goes up to these people, while barking, to smell them and he tail is wagging. Before this she loved all dogs and people and wanted to be greeted by everyone. Then she started barking at my husband when he came to bed. The barks are very short and rapid. We thought she might be territorial of me but now we aren’t sure. We are working on the quiet command with treats and that works sometimes. We set up her crate so if she’s stressed she has somewhere to go but we just don’t know what to do. We hope it’s a phase but I don’t want this behavior to get anymore out of hand than it already has. We are talking her into the vet next month. Any suggestions?
