Simple to use Wont pull up into your dogs eyes Wont turn your dogs head Made of soft but strong material Comfortable for your dog Recommended by dog trainers & behaviourists Made in Britain One piece from headcollar to end of lead. When your dog pulls, both loops tighten restricting the whole head, the dog backs off from the restriction. Only gentle pressure is needed, & there is no need to jerk. The end of the lead features a clip which can be made to form a handle or can be clipped to your dogs own collar forming a loop, which may give new users more confidence, or is good for use on wriggly puppies. Make sure the Gencon is fitted correctly & it is slackening when the pressure is taken off the lead.
