How do you get rid of fleas without spending a lot of money?

Things that will help to reduce a flea problem in dogs: * Feed your dogs garlic ( about 1 crushed raw clove a day in their food for a medium sized dog) * give them a bed of sand to roll in (sharp or paving sand is a good type to use) but make sure it isn't used as a toilet... * brush them daily * wash them regularly * let them swim regularly * change their bedding regularly. Shake it out to disturb fleas at least daily
