I get dog hair all over my work in progress. It's usually not too bad that I can't hand quilt and then just toss in the wash after. It's just one of the many reasons I was my quilts before gifting! If you've tried the sticky rollers and brushes and gotten the hair down to a dull roar (no pun intended here), and it's workable, I would just continue quilting and then wash after you're done.
