I feel sorry for the dog--not you. Honestly, have you even tried to be friendly and patient with the dog?? Why can't dog stay in the same room while you're working on webpage or whatever? Poor little dog had a terrible life until rescued and needs help. I agree with those who suggest dog training for the two of you.

You said dog barks while it is alone. Why can't she stay in the room with you??
You said at night you put dog in laundry room. That sounds very lonely and scarey for dog. I would not want to be shut up in a laundry room with no way out--claustrophobic for me.
You said dog hides under a bush when you go out to yell at her. That would indicate to me that dog is outside and alone. I hope it is not cold... poor dog.

Another option: You could always get your own apartment where they are NO dogs.

I hope this doesn't come off sounding rude. It's just that I find your attitude totally selfish and immature. Do you not have any empathy for what the dog has been through? One needs patience and concern to help this dog AND dog training for the two of you... Kay in NC
