Soft wool against a cold nose marks the start of winter walks, and this canine garment brings warmth to those brisk morning outings. You will find that constructing these sweaters is a rewarding process, as the repetitive nature of the double crochet stitch creates a dense, snug fabric that holds its shape well over time. This project works well for anyone familiar with basic turning chains, offering a chance to practice shaping and sewing pieces together. By adjusting the armhole placement and neck circumference, you can customize this fit for dogs of different builds, ensuring your pet stays comfortable and cozy throughout the season.

Why You’ll Love This Pattern

The Classic Crochet Granny Square is the quintessential building block for handmade blankets, bags, and garments. This project is ideal for beginners because it focuses on mastering the double crochet stitch and working in clusters, which creates a rhythmic, meditative pace. You can easily complete a single square in under twenty minutes, making it an excellent way to use up small amounts of leftover yarn from larger projects. Since each square is small, it is highly portable, allowing you to carry your hook and yarn in a small pouch for stitching on the go.

I finally learned how to make these after months of struggling with other patterns. The instructions were so clear that I made a whole pile of squares in one weekend.

Step-by-Step Pattern Instructions

Granny Square Body

The square is built by working into the center ring and subsequent chain spaces.

Rnd 1: Ch 4, sl st to the first ch to form a ring. Ch 3 (counts as first dc), 2 dc in ring, ch 2, (3 dc in ring, ch 2) 3 times. Sl st to top of starting ch-3. (12 dc, 4 ch-2 spaces)
Rnd 2: Sl st into the first ch-2 space. Ch 3, 2 dc in same sp, ch 2, 3 dc in same sp (first corner made). *Ch 1, skip next 3 dc, (3 dc, ch 2, 3 dc) in next ch-2 space (next corner made). Repeat from * around. End with ch 1, sl st to top of starting ch-3. (24 dc, 4 ch-2 spaces, 4 ch-1 spaces)
Rnd 3: Sl st to next corner ch-2 sp. Ch 3, 2 dc in same sp, ch 2, 3 dc in same sp. *Ch 1, 3 dc in the next ch-1 side space, ch 1, (3 dc, ch 2, 3 dc) in the next ch-2 corner sp. Repeat from * around. End with ch 1, sl st to top of starting ch-3. (36 dc, 4 ch-2 spaces, 8 ch-1 spaces)
Rnd 4: Sl st to next corner ch-2 sp. Ch 3, 2 dc in same sp, ch 2, 3 dc in same sp. *Ch 1, (3 dc in next ch-1 space, ch 1) twice, (3 dc, ch 2, 3 dc) in the corner space. Repeat from * around. End with ch 1, sl st to top of starting ch-3. (48 dc)

Finishing

Fasten off your yarn, leaving a six-inch tail. Use a tapestry needle to weave the yarn end through the back loops of the finished stitches to secure it. If you are joining multiple squares, do not weave in the ends until you have completed the joining process, as those tails can be used for seaming.

Care & Washing Instructions

Machine wash your finished item on a gentle cycle in cold water using mild detergent.
Lay the item flat on a towel to air dry, reshaping it with your hands while damp to maintain the square edges.
Do not iron or bleach, as this may damage the synthetic or natural fibers of your yarn.

Pro Tips & Common Mistakes to Avoid

Maintain consistent tension by ensuring your yarn is not pulled too tightly during the chain stitches, which can cause the square to curl. Use a stitch marker in the top of your starting chain-3 to make it easier to identify the join point at the end of each round. Weave your ends in diagonally across the back of the stitches to ensure they remain hidden and do not work their way loose over time. You can increase the size of the square by repeating Row 4 additional times, adding one more (3 dc, ch 1) cluster along each side for every extra round you choose to work.

Frequently Asked Questions

Can I use different colors for each round?

Yes, changing colors each round is a common way to use scrap yarn. Simply join the new color with a sl st in any corner space at the start of a new round.

Why is my square curling instead of laying flat?

Curling usually happens if your tension is too tight or if you have skipped the chain stitches between clusters. Ensure you are working a ch 1 between side clusters.

Is this pattern suitable for making a full-sized blanket?

Absolutely. You can make as many squares as needed and join them using a mattress stitch or by crocheting them together with a sl st join.

Am I allowed to sell blankets made from this pattern?

You are welcome to sell finished items created from this pattern. Please check the specific terms of the yarn manufacturer regarding commercial use if you intend to label your goods.
