These are the slip leads we highly recommend.
British Style Slip Lead
Simplicity at its best - soft on the hands, easy to use and pliable enough to fit in your pocket. Mendota’s flagship product, used for many years by trainers and handlers, is now available for exercise, training, and field use. Having the leash and collar in one design allows for correction and ease of use. The adjustable leather slide prevents the lead from slipping off, yet allows for release in the relaxed position.
