My dog when put on his leash turns to stone, not moving tail between legs and doesn't move for HOURS. I try to walk, yet he does not move at all. He is a 4 month old mutt. Yet when off the leash he runs like a mad dog :/ Anyone have any tips how I can get my dog to walk when put on a leash, as he refuses to move. And YES I waited there for a few hours he didn't move. Anyone have any ideas?
