On a sidenote, dog hair does have its uses. I met a lady at a craft fair who was a groomer. Her hobby was to gather up the dog hair, spin it into yarn and make scarves and sweaters out of it. She had scarves of poodle, golden retreiver, schnauzer, etc. I'd never buy one, but she had a lot of customers who wanted a scarf to match their dog.
When I brushed our golden retreiver, we always gave the handfuls of soft fluff to my sister's gerbil. The gerbil loved the stuff, it was his absolute favorite to nest with.
