If you have been looking for a cosy project for your furry friend, you are going to love this one. In this tutorial I am going to show you how to crochet a size medium dog sweater, starting at the collar and working your way all the way down to the tail in one go โ no seaming required. Below you will find the full video tutorial and the complete written pattern, so you can follow whichever works best for you.
This pattern uses just a few basic stitches, and because you work it from the top down in a single piece, it is a great project for crocheters who are still building their confidence. Grab your hook and let’s get started.

Tips and Common Mistakes
– The sweater is worked in one piece from collar to tail โ there is no need to join or seam separate sections.
– Ch 2 counts as a dc throughout the body, so do not work an extra dc into the same stitch as the chain-2.
– When working the ribbing in Rounds 3โ10, keep your post stitches consistent: FPdc over FPdc and BPdc over BPdc on every round.
– In Round 20, the chains that create the leg holes bridge over exactly 14 skipped stitches on each side. Count carefully before you skip.
– The tail section begins with slip stitches at Round 33 to reposition the yarn before the decreases start. Do not count these slip stitches in your stitch count.

FAQ
Can I make this sweater in a different size?
The tutorial is designed for a medium-sized dog. To adjust the size, you would change the starting chain count and re-work the increase and decrease sections accordingly. A good starting point is to measure your dog’s neck circumference and chest girth, then swatch to find the right stitch count for your yarn and hook combination.
What does “work into the back bump” mean?
When you look at the bottom of a foundation chain, you will see a row of small bumps running along the back. Working into these bumps rather than the standard V-shape gives you a neater, more even edge at the start of the collar. It is a small step that makes a noticeable difference to the finished look.
What are FPdc and BPdc, and why are they used here?
FPdc and BPdc are stitches worked around the post (the vertical part) of the stitch below, rather than into the top loops. Alternating them creates the raised ribbed texture on the collar, which also gives the neckline a little stretch so it fits comfortably around the dog.
Do I need to sew the sweater together at the end?
No. One of the key features of this pattern is that you crochet the entire sweater in one go, from the collar right down to the tail. The only finishing step is to weave in your yarn ends once you have fastened off after Round 45.
