Recall only really gets tested the day a dog decides not to come back, and a long line is the tool that keeps that decision available to you rather than to the dog.

This is the 10-metre length in Coachi's training line range, made from 3-strand padded webbing for a comfortable grip. Coachi's own listing centres on their 5-metre line as the version aimed at smaller dogs and puppies; this 10-metre length is described as suited to larger dogs and puppies, giving more distance to practise recall in open spaces, socialise a puppy or dog in public, or keep a firmer hold on a newly acquired or nervous dog while it settles in.

What we don't know. Coachi don't publish a breed or weight guide for either the 5m or 10m version, only that the shorter line suits smaller dogs and this longer one suits larger dogs and puppies — so match the length to the space you train in and the dog's size in general terms, rather than a precise chart.

Who it's for: owners of larger dogs or puppies working on recall or public socialisation, and anyone who needs extra control over a newly acquired or nervous dog without keeping it on a short lead.
