This dog jumper from M&S is knitted in a chunky, patterned design with a round neck for an easy, comfortable fit. The regular fit pulls on easily and includes added stretch, so it moves with your dog rather than restricting them. Long sleeves give full coverage along the front legs, helping keep them cosy on cold walks or at home. With its festive pattern, it's a cheerful choice for Christmas, whether that's a family walk or settling by the fire.
