NO HARSH CHEMICALS – Unlike traditional flea shampoos, Richard’s Organics gentle and safe Flea and Tick Shampoo uses 100% all-natural actives to kill fleas and ticks rather than harsh chemicals. Made with 5 pure essential oils, this dog shampoo smells great and soothes irritated skin while it works hard to rid your dog of fleas and ticks. FAST ACTING – You will see fleas coming off your dog as you bathe with Richard’s Organics Flea and Tick Shampoo. Ticks let go and are more easily removed from the skin. For best results, work the lather thoroughly into the dog’s coat and down into the skin, moving back from the head. Allow lather to remain on the dog for a few minutes and then rinse. The essential oils are calming, and your dog will smell great. SOOTHES SKIN: This dog flea shampoo naturally kills fleas and ticks while soothing skin. It does not contain parabens, dye, soap, harsh chemicals, or artificial fragrances or colors. It will not remove topical spot-on flea and tick treatments.
