Question
i have a 9 month old pitbullterrier hes such a nice dog but chews everything i have or what he sees he listens wen he wants to in stead of me taking him  for a walk he takes me for a run hes very naughty and something needs to be donw hes bit me and i dont want him to go for any one els i love him to bits but im getting really upset how can i change him i dint want to lose him

Answer
First of all he needs to be neutered if he's not. Secondly, enroll him in obedience classes ASAP. Your dog is running you rather than you being in charge. Go to alpha dog boot camp (just type it into your web browser and it will pull up the page) and read the whole thing. Lots of times :). Now that your dog has already bitten you , he's way out of control. Get some help from a local trainer immediately. It only gets worse, not better. Find a vet who can recommend someone to get some obedience training started now and who can work with you on a  one to one basis.
Good luck
