After attempting to train lady to walk on a leash using treats, praise, etc, I tried using a choke collar on her. It did no good, it just proved that when she has a scent there's NOTHING that's going to distract her from following it. I thought about a prong collar, but then remembered how she was with a choke collar. (She would literally pull herself hoarse, didn't even think about the collar) I dealt with her pulling for a while, and then decided to try a harness. The harness worked wonders. When she's wearing the harness, I can lead her with one hand, even a couple fingers.
