Luna’s Jacket – Free Dog Sweater Knitting Pattern

Dog wearing a knit jacket-style sweater

Most dog sweaters are built for dogs that can bend their legs easily. Luna’s Jacket isn’t. Ciara at The Fairy Thorn designed this one specifically for dogs with stiff joints – the kind of sweater that goes on without wrestling your dog’s legs into sleeves.

It’s a beginner project. You’ll need chunky weight yarn and a basic understanding of knit and purl stitches. That’s about it.

How it’s built

This is a Ciara design, and it’s clever. The sweater is knitted in rows – back and forth – worked sideways. You start with the flap under the tummy, increase for the back, then decrease for the second side. It fastens under the belly, which means no leg-threading at all.

That’s the whole point. Dogs with arthritis or stiff joints can’t always lift their legs on command. This jacket wraps around them instead.

What you need

  • Skill level: Beginner
  • Size range: Fits dogs 20 to 60 cm in length, adjustable to any width
  • Yarn: Chunky weight

The pattern includes five length sizes and is written to be width-adjustable, so it works for a wide range of body shapes.
