This multi functional lead was designed by Dr Roger Mugford to simplify the training of your dog. The short length is ideal for heelwork training, medium length for obedience training and the long length for recall and distance work. Alternatively, you can use it with the Halti for light, steering control or simply as a normal lead. This lead can be used to walk 2 dogs on one lead, and can also allow for hands-free dog training. Made with soft, padded webbing for extra comfort, this lead comes with a free training guide. Although the Halti Training Lead comes in two sizes, both sizes are the same length (2m) with just the width of the webbing the varying factor. Large: 20mm
