-The Ancol Outside Training Lead has been designed by our friends at PURE Dog Listeners. -This strong line is perfect for allowing dog's freedom while keeping owners in control, and ideal for teaching dogs the recall command. -It is also useful to allow dogs who have not yet learned the recall command to play fetch or run in open spaces, without being in danger of running away or getting lost. -The outside training line is made of sturdy nylon, which is long-lasting, weatherproof and incredibly strong. - This lead is the 15 metre (50ft) lead.
