Don't throw it away!
Here's what I would do. Pull the yarn out of a row until it's at the end. Then, with a needle a little smaller than the one you used to knit it, start to pull out the next row, one stitch at a time. Watch where the loop comes out of and put your needle in the stitch that's there. Do it one at a time all the way across the row.
On regular yarn, there are all kinds of ways to frog efficiently, but on some of the funky, furry yarns, you can't tell what's what.
