Why aren't they bald yet??

Just for kicks, I decided to photograph the dog hair swept up last Monday, Wednesday and Friday..... and here are the pictures:

Monday's sweep --


Wednesday's sweep PLUS Monday's in the background --


Friday's sweep --


Cumulative for five days --


And this is only the hair from the living room, dining room, kitchen and hallway; bedrooms are still carpeted -- and then there's still the stairs and the entire basement. There's enough hair to make an entire puppy!! So the question remains -- why on earth aren't these two bald yet??
