Humans think they are such a big screaming deal with their computers and light bulbs and ice cream sandwiches, but really, they aren't. They are so insecure that most of the time that dogs can't even sit on the furniture. So what? A little hair gets on the chair, I would prefer dog hair to the massive amounts of skin that is shed there when a human sits down. The only thing that separates humans from animals is the level of visible filth they care about.
