A dog shivering at the front door on a January morning is telling you something. Short-coated breeds, old dogs and small dogs all lose heat faster than the walk requires, and no amount of brisk walking fixes it. This jacket is built around the two things that actually ruin a British winter walk: wind that cuts straight through, and rain that soaks in and stays. The nylon outer turns both away and the fleece-lined collar holds warmth in at the neck.

Construction is nylon over polyester, with elasticated trims at the edges so wind is not funnelled up under the coat as your dog moves. The buckle opening matters more than it sounds. It means you fasten the coat around the dog rather than posting a wriggling animal through a hole, which is the difference between a ten-second job and a wrestling match on a cold doorstep. Reflective detailing picks up headlights on unlit lanes.

• Buckle opening for quick fitting
• Six sizes, S to 3XL, in grey, beige or black

On sizing: the fit is decided by your dog's back length, measured along the spine from the base of the neck to the base of the tail with the dog standing, not by their weight. Two dogs of identical weight can need sizes apart.

Who it's for: Short-haired, elderly or small dogs who still get walked when the weather is at its worst.
