That is why when you use this product you do not bathe your pet after application. If you do, you destroy the process.
If you use revolution, you can bath(if you wanted to)after 2 hours of application, because it absorbs into the skin and into their bloodstream. It states it on the packaging that you can bath after 2 hours and the vet also let me. When I got Buddy from the shelter he was really flea infested, I used the revolution, but I had to give a bath because he was covered not only with dead flea's but flea poop too
He has long hair so it was difficult to comb out, and when I tryed it just smeared the poop along his white fur. So I read the pack and called the vet, then I gave him a bath the next day, and as long as you wait 2 hours its okay. But I don't know if thats the case with other flea meds, just the Revolution.
