Size guide

Each coat we sell has its own size chart: the fleece sweater, the puffer vest and the raincoat. Use the chart for the item you are buying. Measuring takes about a minute with a soft tape measure.

How to measure

  1. Chest: around the widest part of the chest, just behind the front legs.
  2. Neck: around the neck, where a collar sits.
  3. Back length: from the base of the neck to the base of the tail.

Measure with the tape snug but not tight, with your dog standing. Between two sizes, size up.

Fleece sweater (XS–XXL)

For our fleece dog sweater with leash ring. Pick by your dog’s chest, not by weight or the size your dog wears in another brand.

XS ≤10.5≤26.7 11.830 7.920 7.920 ≤3.3

Match your dog’s chest to the Dog chest column; the room to move is already in it. Sweater chest, back and neck are the sweater’s own measurements, measured by hand (can vary by about 1 in). Your dog’s neck should be at least 1 in (2.5 cm) smaller than the Sweater neck: the sweater pulls on over the head. Compare your dog’s back with the Sweater back, but still pick by chest. Weight is a guide only.

Puffer vest (XS–XL)

For our zip-up puffer vest with leash hole.

Size Vest chest Vest neck Vest back

XS 11.830 7.519 7.920

L 19.750 12.632 13.434
XL 21.755 1538 15.740

These are the vest’s own measurements from our supplier, measured by hand (can vary by about 1 in). Pick the size where the Vest chest is at least 1 in (2.5 cm) larger than your dog’s chest, and the Vest neck is at least 1 in (2.5 cm) larger than your dog’s neck. Between two sizes, size up. We have no weight guide for the vest: pick by chest.

Raincoat (S–3XL)

For our clear hooded raincoat.

Each row shows the largest dog that size fits. Pick by back length first: the smallest size whose Dog back is at least your dog’s back. Then check your dog’s chest and neck are not over that row’s numbers; if they are, size up. Weight is a guide only.

Not a standard shape? Pick like this

  • Between two sizes: Size up.
  • Wears S or M in another brand: Measure anyway. Letter sizes and weights differ between brands.
  • Round belly or deep chest (Pug, French Bulldog): Measure the widest point and size up if near the top of a range.
  • Big head or thick neck: Compare the neck with the Sweater neck column: it should be at least 1 in (2.5 cm) smaller. If not, size up.
  • Long back (Dachshund, Corgi): Pick the sweater by chest. On a long dog it ends before the tail.
  • Fluffy or double coat: Measure over the fur and size up if near the top of a range.
  • Puppy still growing: Size up for room to grow.
  • Under 2 lb (chest under 8.5 in): XS may be roomy. Send us the chest first.
  • Over 21 lb (chest over 20.5 in): Too small for the sweater; XXL is the largest.
  • Cat: Same rule: measure the chest, not the label size.
  • Buying as a gift: Ask for the chest size, or lay a sweater that fits flat: 2 × its width under the arms, then compare with the Sweater chest column.
