Size guide & how to measure

Pet coats and jumpers are sized mainly by back length, with chest girth as a second check. Back length matters most for coverage.

How to measure

  1. Back length: measure along the spine from the base of the neck (collar area) to the base of the tail.
  2. Chest: measure around the widest part of the ribcage, behind the front legs.
  3. If the two measurements suggest different sizes, choose by back length and allow for the chest.

XS20–25 cm30–40 cm
S25–32 cm38–50 cm
M32–40 cm48–62 cm
L40–50 cm60–76 cm
XL50–60 cm74–92 cm

Ranges are approximate and vary by style. Always check this product’s Specifications for its exact measurements.

Full description

There is a difference between a costume and a jumper, and this sits firmly on the jumper side. It is a warm knitted layer with a seasonal design worked into it, so the dog can wear it for an evening walk in October rather than for four minutes and a photograph. That makes it one of the few pieces on this page you might reasonably buy twice, because it earns its keep after the pumpkins have gone.

The design comes in four finishes, and they are not the same garment in different colours. Plain orange and a small pumpkin print are straightforward, while the black jacquard has the pattern knitted into the structure of the fabric and the black embroidery has it stitched onto the surface. Jacquard tends to hold up better to washing because there is nothing sitting on top to catch or pull, which is worth knowing if the dog in question rolls in things.

  • Four finishes: orange, orange small pumpkin, black jacquard, black embroidery
  • Warm knitted construction, cut for leisure wear rather than dress-up
  • Five sizes from XS to XL
  • Twenty size and finish combinations listed
  • Cut for teddy-coat breeds and similar builds
  • Seven photographs across the finishes

On sizing: knitwear on a thick-coated dog runs tighter than the chart suggests, because the chart was not measured over a cockapoo in full coat. Measure back length from collar to tail base over the coat as it currently is, and if your dog is between sizes take the larger. Check under the front legs after ten minutes for rubbing, which is where knitted jumpers usually go wrong.

Who it's for: owners of small and medium dogs who feel the cold, who want something seasonal that still works as an ordinary jumper in November.
