You can buy 20 Mule Team Borax in the grocery store. It's in the laundry detergent section. If you are looking for a non-toxic flea "dip" for a puppy or a grown up, use vinegar! It works like magic. I put my guy in the bath tub and really give him a rinse with it, any flea jumps off like they were set on fire. I towel off the boy, then rinse the tub with Clorox. Mickey only smells like an Easter egg until he dies completely, or I sometimes follow up with a No-More-Tears shampoo if he needs it.
