try adding some vinegar to his drinking water...that helped a lot when my mom\'s dog got \"infected\" with fleas..

I second what Lara says about the vacuuming for the house.  Just be sure to throw away the vacuum bag - outside of your house - immediately.  I did this for 3 days in a row and the fleas were gone.  I guess the only difference is that my pets are indoor only....but I\'ve got critters who run around the apt. complex and come up to my patio screen, so there\'s still the potential for new fleas to arrive.  BUT....I use Advantage on the cats.
