Crochet Pet Harness Patterns: 11 Free Designs

Genuinely free, full-instruction crochet pet harness patterns are surprisingly hard to find online, most “roundups” of this topic end up linking the same handful of sources. After checking dozens of leads, these are the real ones: five with full written instructions, and six video tutorials from designers around the world (Spanish, Korean, and Portuguese-language channels included) who never wrote up a blog post but do walk through the full construction on camera. Open each source before choosing one, and note that a harness is one project where getting the fit right matters more than exact yarn substitutions.

A hook you already know well and cotton yarn, since it won’t stretch out under a leash pull the way acrylic can, cover most of what these patterns ask for. A few also call for small metal D-rings or a buckle, which you’ll need to source separately since they’re hardware, not yarn.

Pet harness patterns to explore

1. Max’s Dog Harness

Designer Sara Sach of Posh Pooch Designs covers the widest size range of any pattern here, XXS through M for dogs from 2 to 15 pounds, in worsted weight with two D-rings set into the belly band so the leash clip never snags fur. An optional decorative bow at the neckline is the one purely cosmetic touch on an otherwise practical build.

2. A Crocheted Dog Harness for Your Tiny Dog

Pixie HeartStrings designed this one for her own Chorkie under 5 pounds, an 8-inch neck and 13-inch chest as written, with notes for adding or removing rows to fit a different dog. The construction is genuinely different from most: a triangular chest plate built by decreasing stitches, with three straps extending out to the neck and legs rather than one continuous band.

3. Easy Dog Harness

Luvs2knit built this as a step-in style, sized for a Shih Tzu, so the dog steps through both leg openings before you clip the ring on top of the back rather than pulling anything over the head. The designer notes you can repeat two of the rows to size the straps up or down for a different dog.

4. Quick and Easy Dog Harness

Crochet With Julie specifically chose cotton for this one since it holds its shape under a leash pull better than acrylic. The written instructions cover the setup and strap construction, then hand off to the companion video for the finishing details on how the two straps join, so plan to watch alongside reading this one.

5. Simple Small Dog Harness

StringsandThingsByJoyce offers a genuinely minimal pattern for small dogs, gauge isn’t critical, and it’s a free download on Ravelry rather than a blog post. Worth including for how little it asks of you: a tape measure, a 5mm hook, and yarn, nothing else.

6. XXS Teacup Size Dog Harness

Kaylin Cierra Rose made this one out of necessity: her 5-pound dog Bambi had outgrown a harness meant for a kitten and couldn’t find anything smaller made for dogs specifically. The materials list is genuinely tiny, one skein of cotton, a 3.75mm hook, and a 1-inch buckle, and the video walks through the full build step by step.

7. Aprende a Tejer un Arnés para tu Mascota

This Spanish-language tutorial from the Crochet Hook channel walks through a functional, decorative harness meant to double as something nice enough to actually be seen in. If you don’t speak Spanish, auto-generated captions or auto-dubbing get you through it, and the visual construction is easy enough to follow either way.

8. Crochet Dog Harness Tutorial

Yvonne loves crochet!! adds a lace panel to this harness, a detail none of the other patterns on this list attempt, for a result that reads more like an accessory than pure function. The full build runs about 20 minutes on video.

9. Dog Harness (Chest Harness, Leash)

This one from Korean channel 코바늘하나로 is the most-watched dog harness tutorial we found anywhere, at 88,000 views, using mixed yarn and a size 6 hook. It covers both the chest harness and a matching leash in one sitting, so it’s the pattern to pick if you want the full set rather than just the harness.

10. Crochet Knitted Harness for Kittens and Puppies

Los Pollitos Tejen designed this one to fit either a kitten or a puppy, useful if you’re making harnesses for more than one small pet and want a single pattern that covers both. It’s one of over 150 tutorials on the designer’s channel.

11. Peitoral de Crochê para Cães e Gatos

Helena maria vlogs gives specific guidance on measuring your own pet’s chest circumference before you start rather than working to fixed numbers, which makes this Portuguese-language tutorial one of the more adaptable options here regardless of what size dog or cat you’re fitting it to.

Choosing a dog harness pattern

If you want exact stitch counts to follow on paper, start with Posh Pooch Designs or Pixie HeartStrings, both of which cover a genuine range of small-dog sizes. If you’d rather watch the construction happen in real time, the six video tutorials above cover everything from a bare-bones build to lace detailing to a matching leash, and language isn’t really a barrier since the stitches are the same regardless of what’s being spoken over them. Whichever you pick, measure your own dog’s neck and chest before starting rather than trusting a listed size, since fit varies more between individual dogs than between breeds.
