When applying Permethrin on your dog, wear rubber gloves or mitts for protection. Start spraying at the tail, covering the entire body, including the legs and underbody. Fluff the dog’s hair to ensure the spray reaches the skin, but avoid over-saturating. Be careful not to spray near the dog’s eyes, face, or genital area.
