What is good local dog training service? I have pitbull/bassethound mix that has some leash and dog problems. Whenever he sees another dog, he loses his mind to get to it. He will charge after anyone on any kind of scooter/bike. He isn't normally aggressive at all, however he does display aggression towards the bikes; Be it a bicycle or motorcycle, He freaks out. He already knows basic commands and listens well. It's just a leash problem.
