our house doesn't have a dog smell yet, big yet!, but my parent's does. they use fabric softener sheets ALL around their house. they buy a new box everytime they buy a box for actual laundry. they hide a sheet (for about a week) in baskets, behind the phone, in a drawer of a desk, in the flower thing above the door, in the curtain swag on windows, in the couch, EVERYWHERE you can hide something, one is there! their fave is a lavender scented one. pretty neat huh?! i read it in i think a woman's magazine for a car scent and told them about it and they have used it for about 7 years now!!! we use the fabreeze meadows one in our dresser drawers instead of saches bags.
