I am literally at my wits end. My boyfriend went and got a pit bull puppy over the summer, brought her home at 7 weeks old. I warned him against this, as we both work full time jobs. She is almost 6 months old and still keeps me up literally all night crying in her cage. My boyfriend works midnights so he does not have to deal with this, but it has been months and I am barely surviving on 3-4 hrs of sleep a night. At this very moment, she has been crying for an hour and thirty four minutes in her crate. I have been using the crate since he first brought her home, acclimated her, she always has things to chew on and she is thoroughly exercised throughout the day. Over the weekend my boyfriend got her off of the couch to put her in the crate so we could go to bed and she bit him in the face. I just do not know how to handle this behavoir. I have had rottweilers and a german shepherd in the past and have never dealt with the things I am dealing with from this dog. I am beginning to think there is nothing that can be done.
