Hi My son and I have two dogs an aussie shepard mix and a brown nose pit I think thats what he is.Anyways he used to live in Arizona with my son and his dad. My son now lives here in Washington with me. He brought his pit bull everything seemed okay then one night the dogs got into a fight in the hallway don't know what happened it was 3am my room mate walked out of his room right when it started and got bit by buster (pit bull). We thought it was an isolated incidence then a few months later my sons friend was over and he bent down to pet buster he jumped up and nipped his cheeck once again we thought it was human error the way his friend approached the dog. Then one day my older son came over he never knocks he just comes in well the dogs were barking and going nuts I was in the shower when I came out my son was screaming because buster was attacking him bit his foot and elbow. Well that was it I was terrified that he was going to really hurt someone so I hired a specialist to come out and meet buster she gave us strict instructions on how to care for him and we haven't had any more bad problems with people but it is alot of work when someone comes over. We live in a duplex and have neighbors down stairs when they come home you can see them out the window and hear them close the car doors. When buster hears or sees them he starts to freak out I usually can distract him or contain him but lately he has been redirecting his anger at my shepard mix. Yesterday she was in the kitchen and he was in the living room having a fit because the neighbor came home I tried to get him to relax but he had that look in his eyes and I knew it was too late so I asked him to sit he did I went towards him to grab his collar and he ran past me and attack my dog it was a really bad fight, my dog has a punture wound on her side and in the past she has really hurt him also. She seems traumatized my the event and hasn't come out of the bedroom all day except to go potty. My son left for the day and took buster with him but Im not sure what to do with him. I don't want to put him to sleep but he seems way out of control and I don't have the skills or the time to fix his problems and I know my son doesn't either he is in his late teens but not very responsable. What do you guys think we should do, you all love pit bulls would you put your pitty to sleep???
