I vacuum my home every day, often more than once. I have two dogs, and the big one has lots and lots of long black hair. Hair he happily drops all over the main floor of our house and leaves on the furniture, too. We then sit on the furniture, the fur sticks to our clothes, and we drop it on the stairs on the way up to bed at night. And before you ask, the big black dog gets brushed and Furminated and raked regularly. The hair amount pretty much stays the same. Our little dog barely sheds at all. Both big and little pups like to roll around in the yard several times a day, though, and then come in and shake their coats. So then I get pieces of grass and weeds, and sometimes even bugs all over the floor. And because New Jersey is the home of lots of sand and my husband refuses to use any but the back and side doors, he happily tracks in lots of dirt and sand every day, often several times a day.
