After pulling my dogs shedding undercoat off him for the past few weeks or so, along with vacuuming daily and getting full buckets of hair off the carpet I got to thinking...Has anyone tried using dog fur, perhaps just the undercoat, as a substitute to down? Maybe like a poor mans down if you will? I figure you could harvest it yourself if you have a dog via a vacuum and comb, and just use it as stuffing for any DIY bags, quilts, vests, etc.
I know I saw a news clip where someone made a sweater out of dog fur so I know it's possible. I'm just wondering where it ranks on the warmth, loft, compressibility, usability, etc scale.
