This line is purpose made for Canicross. It is extremely light in weight but ultra durable. Ideal for handling dogs who know how to work in harness. 
Made out of 1 inch wide tubular webbing with built-in bungee.
It has a brass trigger hook at one end to connect to the dog harness with a small loop at the other for attaching to a Canicross or walking belt via carabiner or panic snap.

Please note these have recently moved from being a small loop to a handle some of the lines in stock still have the original small loop.
