This lead is a double ended lead and can provide great aid while you are training loose lead walking. With the adjustable length you have the opportunity to make it suit to any dog walking situation without needing to wrap it abound your hand.
Wrapping the lead up can actually give signal to your dog to react as your tension transferring down to the dog through the lead. With having a free moving handle and being able to adjust the length you can avoid unhelpful reactivity.
Also can be used as a single lead attaching one clip to the handle making a full lenth lead.
