K9 Advantix is a monthly spot-on treatment for dogs that combines imidacloprid and permethrin to kill fleas, ticks and mosquitoes and repel them before they bite. It needs no prescription and is applied to the skin at the back of the neck every 30 days. Its main advantage over flea-only drops is the added tick and mosquito coverage, which matters most for dogs that hike, camp or live in tick country. The trade-off is that permethrin is toxic to cats, so households with cats need to keep treated dogs separated until the application site dries.
