Small, short-coated dogs lose heat faster than their owners tend to expect, and a knitted layer does more for them on a January walk than any amount of brisk pace. This is a proper cold-weather jumper rather than a novelty piece: striped knit, a hood that pulls up when the wind turns, and a fur bobble on the back that is admittedly there for your benefit more than your dog's. It pulls on over the head and front legs, which is the quickest way to dress a dog who does not enjoy being dressed.

Knit holds warm air in the spaces between the stitches, which is why a jumper feels warmer than its weight suggests, and also why it is the right choice for dry cold and the wrong one for heavy rain. Wet knit stays wet and pulls heat out of the animal wearing it. Treat this as an indoor and dry-day layer, with a waterproof coat over the top, or instead of it, when the weather is genuinely foul.

On sizing: chest girth decides the fit, not your dog's weight. Measure round the deepest part of the chest just behind the front legs and check that against the size guide before ordering. Knitwear also snags, so keep it away from hedgerows and rough play, and take it off for anything unsupervised, since a hood and a loose knit are both things a bored dog can get tangled in.

Who it's for: Small and toy dogs who feel the cold indoors and on dry winter walks.
