Yarn & Materials for This Crochet Dog Sweater
This pattern is made with Red Heart Super Saver yarn — a worsted weight (#4) acrylic that’s machine washable, durable, and comes in a wide range of colors. You’ll need 4 contrasting colors to create the colorful fair isle stranded yoke. If you’d like to substitute, use any worsted weight yarn in 4 colors; machine-washable acrylic is strongly recommended since dog sweaters need regular washing!

- Hook: Size H/8 (5.0mm) or size needed to obtain gauge
- Sizes available: Small / Medium / Large
- Skill level: Intermediate — experience with colorwork/fair isle recommended

Video Tutorial: Crochet Dog Sweater with Fair Isle Colorwork
In the video tutorial below, I walk you through how to read this intermediate crochet pattern, how to use the colorwork chart, and how to work the stranded fair isle crochet technique. Since this pattern is labeled intermediate, the video assumes you already have a solid grasp of basic crochet and focuses on the more complex colorwork sections.
Note: the video covers the yoke colorwork section in detail. The body and edging are more straightforward, so if you can handle fair isle crochet, you’ll be able to finish those sections confidently on your own.
I made the size small in the video for my chihuahua, Lucy. I used a different color on the leg ribbing than the pattern suggested — and I was so excited to try it on her. But it turned out too small!
Word of caution: always measure your dog before choosing a size. See the measuring guide below!
How to Measure Your Dog for a Sweater
Measuring your dog is the most important step before you start crocheting! Every designer sizes their patterns slightly differently, so always compare your dog’s actual measurements to the finished dimensions in the pattern — not just the size label.
Take three key measurements with your dog standing up (not sitting):
- Back length: from the base of the neck to the base of the tail
- Chest circumference: around the widest point, just behind the front legs
- Neck circumference: where the collar normally sits
When in doubt between two sizes, size up — a slightly loose sweater is far more comfortable for a dog than a tight one.

Frequently Asked Questions
How do I measure my dog for a crocheted sweater?
Take three measurements with your dog standing up: back length (base of neck to base of tail), chest circumference (widest point behind front legs), and neck circumference (where the collar sits). Compare to the pattern’s finished measurements and go up a size when between sizes — a slightly loose sweater is always more comfortable than a tight one.
What yarn is best for a crochet dog sweater?
Machine washable is non-negotiable — dog sweaters get dirty and need regular washing. A soft worsted weight acrylic like Red Heart Super Saver is ideal: affordable, durable, gentle against dog skin, and fully machine washable. Avoid anything that sheds excessively (dogs groom themselves and could ingest fibers) or feels scratchy or stiff.
What size should I make if my dog is between pattern sizes?
Always go up a size. A slightly loose sweater is far more comfortable for a dog than a tight one — dogs need freedom to move, breathe, and just be dogs. If length is the issue, you can often add or subtract a few rows from the body section to customize the fit without affecting the rest of the pattern.
Will my dog actually wear the sweater?
It depends on the dog! Some dogs love sweaters and seem genuinely comforted. Others are miserable. Introduce it gradually with lots of positive reinforcement and treats. Start with short wear times and increase slowly. If your dog freezes, walks awkwardly, or keeps trying to shake it off — respect that and take it off. A dog’s comfort comes first.
Are crochet dog sweaters appropriate for all breeds?
They’re most beneficial for small dogs and short-haired breeds who genuinely need the warmth — Chihuahuas, Italian Greyhounds, Whippets, Miniature Pinschers. Large double-coated dogs (Huskies, Malamutes, German Shepherds) generally don’t need sweaters and can actually overheat. Always prioritize your dog’s temperature and comfort over the fun of dressing them up.
Is this crochet dog sweater pattern beginner-friendly?
This pattern is rated intermediate due to the fair isle stranded colorwork in the yoke. If you’re new to colorwork, I’d suggest practicing the technique with a smaller project first — like the Mallow Mosaic Hat — before tackling the dog sweater. The body of the sweater is very straightforward; it’s the colorwork yoke that requires attention.

Love this! My friend wants me to make a sweater for her three pound Chihuahua but since she lives in another state I’ve been reluctant. Would you say the size you used for Lucy would be good?
