Basic Leashes by Mendota Pet. Details: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 adapted 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 it to be released in the relaxed position.
