my first huge success of 2009 (and I don't mean because the sweater itself is large!).
Knit of Berocco Comfort Worsted Weight in fire engine red, it's sized to fit a dog 31" from base of neck to tail. It took nearly 4 full skeins of yarn.
It's all done in a simple rib, beginning with the collar in the round. There is a cute little hole at the base of the collar section to accommodate a leash. Then the rest is knit flat, though with lots of increases and decreases. The belly panel is knit on one side of the flat piece, and buttons around the dog.
Thanks to Terri Lee Royea, whose free pattern on Ravelry I adapted for this sweater.
