Advantage Aqua for Dogs 8.8-22lbs (4-10kg) is a spot-on that is applied on the back of your dog's neck once a month for the treatment and prevention of fleas. Simply squeeze the contents of the tube onto the skin on the back of your pet's neck. Advantage then spreads over your pet, remaining in the oily layer of the skin, where it is effective against fleas all month long.
