Is dog hair good for anything?

I have got to find and ingenius use for dog hair. I pick up so much dog hair every night it's unbelievable. Sometimes we have to sweep 2 or even 3 times a day! And even then, we can't get it all. There has to be something dog hair is good for. If I could sell it, I'd be a very rich woman.

Would a dog hair sweater be too much?

(Yes, these people really did make sweaters from the hair of their dogs. I shudder to think of it.)
