I sweep the main floor of our house daily. Casey and I have a ritual, I take out the broom and she positions herself directly behind my sweeping activities, to supervise of course.
As I sweep, she walks behind me, dropping hair on the floor with each step. I'll complete a full circle around the house, and upon walking back around to where I just swept, find a nice trail of fresh dog hair exactly where I finished sweeping. In 24-hours time, huge hair-balls will have accumulated down the main hallway and in the corners by the end tables of our living room. I could wash and furminate her, vacuum the entire main floor, and wash all her bedding, and in 24-hours there will still be huge hair-balls in every corner of the house.
I love sweeping up her hair into big piles. It's satisfying in a really disgusting kind of way.
