I have a 4 yo bulldog that gets very aggressive in the morning when my husband leaves for work. We all sleep in the bedroom with the door closed. The alarm sounds and my husband gets up and leaves the room. I stay in bed and Arthur the bulldog is in his dog bed. My husband used to like to come back in the room before he left for work to say goodbye. Now if he comes in Arthur starts jumping, spinning in circles, snarling, barking and will nip us if we go near him. My husband gets very angry and starts yelling which makes Arthur even more wild. Even if he says goodbye from the other side of the closed door Arthur goes crazy. As soon as my husband leaves Arthur is calm again. When he comes home at night Arthur is glad to see him and they spend most evenings hanging out together. When I leave the house he never acts that way. This has been going on for quite a few months and I don't know how to fix it. Thanks for any suggestions you may have.
