Hairless and short-coated pets are not being fussy when they go looking for the radiator. A sphynx, a whippet or a thin-coated small dog genuinely loses heat faster than a double-coated animal does, and in a British house between October and April that adds up to real discomfort rather than a fashion problem.

This is a waffle-knit with a roll-neck collar and enough stretch to pull on over the head in one motion, which is the difference between a jumper that gets worn every day and one that stays in the drawer. The waffle texture traps a layer of air, so it gives warmth without bulk, and the roll neck covers the throat and chest, which are the parts a short-coated animal feels the cold in first.

• Soft waffle-knit fabric with a warm roll-neck collar
• Stretchy enough to pull on in seconds
• Suits both cats and small dogs
• Especially useful for hairless and short-coated breeds
• Sizes from XS to 2XL in blue, sapphire blue and purple
• Weighs between 150g and 200g depending on size

On sizing, honestly. As a general rule, a jumper should let your pet walk, sit and squat normally, with no pull across the chest and nothing bunching up under the front legs.

Who it's for: Owners of sphynx cats, whippets, greyhounds and other short-coated or hairless pets who want a warm layer that goes on without a fight.
