Barking dog.

There is an apartment building across the street from us. About six month ago this guy moved in with a pit bull. I have only seen the dog outside once in that time. The poor dog barks and howls non-stop whenever the owner is away which is most of the day. I have to wonder if the dog is going to the bathroom all over the house or if the guy is expecting it to "hold it in" until he returns. The dog sits at the open upstairs window and just barks and howls for hours. At around 10 pm each night the owner returns and all the noise stops. I just feel really bad for the dog...
