I have a 3 year old Pit Bull that is over wieght(about 90 pounds) and I feel like i tried everything to get him to a heathly weight agian. This includes daily walks, daily play, pulling, and dieting. I am getting worried more and more due to he can't even reach his butt to strach it and has issues backing up. I do not want to see him like this any more and have the time and money to do something I have not tried yet. He is a very active and happy dog. I do have to be carefull with what i feed him becuase some things seem to make his dry skin worse.
