My housemate has just moved into a shared house of four, with her two year old untrained dog. The dog, in two days, has raided all the bins in the house, stolen a housemates dinner (not left out, jumped up on him and snatched it) ripped open and eaten half of my dogs bag of dry food, bullied my dog constantly, and bitten me twice. I have tried to be patient but after being bitten on the hand today, and almost bitten on the face, all because I was holding a stick away from him that my dog had brought to me, I have had enough. My other house mate has also expressed they share my feelings and asked me to speak to her. She shows no control over the dog, or willingness to discipline him. I can't see any other way forward but to insist that he is directly supervised by her, at all times, or kept in her room with the door shut. This seems dramatic but I don't know what else to do. It is not our job to train the dog, and I don't think its fair on myself or my housemates to have to always keep our doors shut, our trash in our cupboards etc. The dog has zero respect or fear, and will do what it wants regardless of being yelled at, I have had to physically drag it out of my room while it was bullying my dog by its scruff, while it tried to bite me.
