I found a great bug repellant at our local "natural" pet supply store...got it for the puppy whom I can't put any flea stuff on yet because she's too small. Anyway, the company's called "Dirty and Harry" and it's green tea and lime bug and flea repellant. No chemicals, good for the dogs AND the humans, no rashes, no asthma, no bites. GREAT stuff! And smells good to boot!
