There is a narrow window in a British summer where a thin vest actually earns its place: early mornings that are cooler than the afternoon, and indoors when a short-coated dog is lying on a tiled floor. This light pink peach-print vest with ruffled sleeves is cut for exactly that, and also for the more honest reason most people buy one, which is that it looks lovely on a small dog.

The fabric is thin and stretchy, so it pulls on without a wrestling match, and the cut is a simple vest with no fastenings to work loose during the day. Weights run between 28 and 51 grams across the size range, which tells you how little there is to it. That matters, because a thin garment on a warm day is close to neutral. It will not cool your dog, but nor does it trap heat the way a lined coat does.

On sizing and on heat. Measure back length from the base of the neck to the base of the tail, and chest girth at the widest point behind the front legs. Weight is a poor guide, and every maker sizes differently. And to be plain about it: nothing you put on a dog cools them down. On a genuinely hot day the answer is shade, water and walking early in the morning, not a vest.

Who it's for: Small dogs on mild days, indoor wear and photographs, where the point is the look rather than the temperature.
