My dog Reggie is actually quite small, weighing in at a whopping 13 pounds. I only clarify it because he actually photographs much larger, something that more than one person has remarked upon. People who see photos of him and then see him in person are usually quite surprised. Even though I am not sure it's directly related to his size, he does always seem to be cold in the winter. He will usually just hang out in his bed or underneath a chair - two spots that are right next to the heating vents. Since he loves the green blanket I knitted, I decided to knit him dog blanket to go with his dog bed.
I used the seed stitch for this blanket because it adds some texture and is so easy to do. While I am not sure this size blanket would fit every dog, this has worked perfectly for Reggie. Sizing it up wouldn't be too difficult either. As it stands, this blanket is incredibly easy to complete.
Knitting needles size 13 with chunky yarn (I used Lion Brand Chunky Yarn in Wheat)
Cast on 100 stitches.
Row 1: K1, P1, K1, P1 - continue until row is complete
Row 2: P1, K1, P1, K1 - continue until row is complete
Row 3: K1, P1, K1, P1 - continue until row is complete
Row 4: P1, K1, P1, K1 - continue until row is complete
Continue Row 1-4 until you reach row 70
Use row 70 to cast off.
Note: for a larger dog, just increase the size. Cast on more stitches and go past row 70 before casting off.
The good news: Reggie seems to really like it!
