Tying a dog up outside a shop usually means unclipping the lead from the collar, threading it round a post and clipping it back on, with a loose dog for the several seconds that takes. The buckle on this handle locks shut instead, so you pass the handle around a post, bench or hook and close it with the dog still attached at the other end. Nothing gets unclipped and nothing gets fumbled.

The rest of the time it works as a completely ordinary walking lead, which is the point: there is no second item to remember or carry. Two widths are offered, 15mm for smaller dogs and lighter handling and 25mm for a bigger dog and a fuller grip in the hand, and the four colours are chosen to match the Canny Collar range if you already use one. The lock is a mechanical buckle on the handle rather than a clip that could be nosed open.

• Locking buckle on the handle for tethering without unclipping
• Works as a standard everyday walking lead
• Two widths, 15mm and 25mm
• Four colours: black, blue, red and purple
• Colour-matched to the Canny Collar range

Be clear about what the lock does. It stops the lead coming free from the post, and that is all. It does not stop a determined dog chewing through the lead, it does not stop someone unbuckling it, and it does not make an unattended dog safe. Tether within sight, for a minute or two, and never in a spot where a stranger could reach your dog before you could.

Who it's for: Owners of Labradors, Border Collies, Golden Retrievers and Cocker Spaniels who regularly need both hands free for a moment.
