The A to B lead walking game is designed to encourage your puppy to stay calmly behind you as you move in one direction. As you walk, focus on keeping your puppy positioned behind the line of your legs, and deliver the reward by placing the treat on the ground about a metre behind you. This helps your puppy learn that the reinforcement happens behind you, not in front, so there’s no need to rush ahead or pull. Over time, your puppy will begin to predict where the reward appears and choose to stay in that position, making loose lead walking more natural and relaxed.
