Crochet Dog Sweater: Free Pet Sweater Pattern

A crochet dog sweater is one of the most useful things you can make with a skein of yarn. Short-haired dogs genuinely feel the cold, and a handmade sweater keeps them warm on winter walks while looking absolutely adorable.

This free crochet dog sweater pattern is a simple pullover in worsted-weight yarn with a 5 mm hook, written in three sizes. It is also a first for CrochetRooms: we have covered baby sweaters before, but this is our first pattern made for a four-legged friend. Below I explain how to measure your dog, the three sizes, yarn and hook choices, and fit tips. At the end, you can grab my free crochet dog sweater pattern as a printable PDF.

Why a Dog Sweater Makes Sense

Not every dog needs a crochet dog sweater, but many do. Greyhounds, Chihuahuas, Dachshunds, and other short-haired or small breeds lose heat fast, and older dogs of any breed feel the cold more. A crochet dog sweater takes the edge off a frosty morning walk and keeps a shivering dog comfortable.

A crocheted pullover is ideal because it stretches. Dogs move, run, and roll, and the natural give of crocheted fabric moves with them instead of binding. This pattern is worked top-down in the round with shaped leg openings, so there are almost no seams to rub. It makes a wonderful gift for a dog-loving friend, too.

How to Measure Your Dog

Fit is everything with a crochet dog sweater. Grab a soft tape measure and your dog’s favorite treat, and take these three measurements while your dog is standing.

Neck Circumference

Measure around the neck where the collar sits, just below the ears. Keep the tape snug but not tight: you should be able to slip two fingers under it.

Chest Circumference

Measure around the widest part of the chest, just behind the front legs. This is the most important measurement. Add about 1 to 2 inches (2.5 to 5 cm) of ease so the sweater is comfortable rather than skin-tight.

Back Length

Measure from the base of the neck to the base of the tail along the spine. The sweater should end around the mid-back to the tail base: long enough to cover the belly area, never longer than the tail base.

Three Sizes: S, M, and L

The pattern covers three sizes based on the standard dog sweater sizing used by popular pullover patterns. Pick the size whose chest measurement is closest to your dog’s, since the chest decides the fit.

Size S fits neck 11 inches (28 cm), chest 18 inches (46 cm), back length 12 inches (30 cm): think Chihuahua, Yorkie, or Miniature Dachshund. Size M fits neck 13 inches (33 cm), chest 22 inches (56 cm), back length 16 inches (41 cm): think Beagle, French Bulldog, or Cocker Spaniel. Size L fits neck 17 inches (43 cm), chest 28 inches (71 cm), back length 20 inches (51 cm): think Boxer, Labrador, or similar medium-large breeds. A comparable pullover dog sweater on LoveCrafts uses the same five-size family this chart is drawn from.

Yarn and Hook Choices

Use worsted-weight (#4) acrylic. Dogs roll in mud, shake off rain, and need frequent washing, so washability beats luxury here. Avoid wool if your dog has sensitive skin, and skip fuzzy novelty yarns that shed. You need about 250 yards for size S, 350 for size M, and 600 for size L, which follows the standard rule of multiplying chest by back length to estimate yarn for a dog sweater.

The hook is US H (5.0 mm), with a gauge of 15 stitches and 7 rows to 4 inches (10 cm). The classic Crochet N More dog sweater uses the same worsted-weight and hook family, which is why this pairing has worked for makers for years. If you also crochet for people, you will recognize the construction from our crochet cardigans: a yoke, shaped openings, then straight body rounds.

Fit and Comfort Tips

A good crochet dog sweater is snug but never tight. You should be able to slide two fingers under the collar and the belly band. The leg openings should sit just behind the front legs without pulling when your dog walks. If the sweater creeps forward, the neck is too loose; if it twists, the chest is too roomy.

Introduce the sweater with treats and short wearing sessions, the way you would a harness. Most dogs accept a sweater within a day or two, especially when they notice how warm it is outside. Never leave a dog unsupervised in a sweater, and skip the sweater indoors once the house is warm. For a human layering piece to match your pup, see our crochet jacket.
