After applying a spot-on flea treatment to your pet, you should wait at least 48 hours before bathing your dog. Also avoid letting dogs swim during this time or getting completely soaked in the rain (easier said than done sometimes!). Repeated bathing after 48 hours can still reduce the efficacy of some spot-on treatments, so don’t wash your pet too often, especially not with a Flea Shampoo. Washing before applying a spot-on can also reduce the efficacy as it will reduce the skin oils which help spread the spot-on over your pet’s body.
