By attaching it, you get a leash that will quickly get your dog out of the habit of unpopular pulling when going for a walk together. By attaching the adapter, an ordinary leash used in protection work becomes a leash that promotes your dog's commitment and motivates him to do better access work. It is therefore the ideal solution for protection service or advanced training. The elasticity of the adapter avoids possible joint injuries. The maximum stretch of 50 cm avoids "pulling back" and also makes it easier for the protection worker to estimate the necessary distance.
