I called these guys because my Rottie was really hyper, tearing up the house, torturing my wife's cat, our walks were horrible, and he needed some obedience. JJ came, the first day we seen awesome results. Its been 4 weeks and hes behaved a lot better. JJ did awesome work with him. He dont pull on the leash anymore, he's not chewing, I dont have to worry about leaving him alone in my home anymore. Very impressed.
