All about this product

Product description

Movement is what sells a spider. A flat printed web sits still on the back and reads as a pattern, whereas stuffed legs mounted on the body bounce with every step, and that small independent motion is what makes people look twice as your dog trots past. It is the same trick that makes a plush toy interesting to a dog, applied to a costume, and it works better than any amount of printing.

The body is soft and plush rather than stiff, so it sits down onto the back instead of standing away from it, and the legs are attached along the sides where they can move freely. Two sizes are offered, small and medium, which tells you plainly that this is made for cats and small dogs rather than anything larger. Soft construction also means it packs flat and comes out of the drawer next year without a permanent crease across the middle.

  • Plush body with soft stuffed legs that bounce as your pet walks
  • Legs mounted along the sides for free movement
  • Two sizes: small and medium
  • Made for cats and small dogs
  • Soft enough to pack flat between seasons

Two things worth knowing. Stuffed legs look exactly like a toy to a dog, so expect this to be chewed the moment your back is turned, and treat it as a supervised costume rather than something to leave on.

Who it's for: owners of cats and genuinely small dogs who want a costume with some movement in it, and who will take it off rather than let it become a chew toy.

Why we chose it

Stuffed legs mounted along the sides bounce as the animal walks, and that movement is what makes people look twice. Only two sizes, small and medium, so this is a cat and small dog costume.

— Matt, founder

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.
