Kills adult fleas, eggs and larvae. Biting fleas are more than just a nuisance for your dog. Left unchecked, they can cause serious disorders such as flea allergy dermatitis, secondary skin infections, tapeworms, and even anemia. This topical flea treatment lets you stop fleas before they become a problem. Used just once a month, it stops fleas from biting in less than five minutes, killing 98 to 100 percent of the fleas on dogs within 12 hours, and keeps working for a month. The dead fleas can't lay eggs, and the dead larvae can't hatch, breaking the flea's life cycle and halting the infestation in its tracks. A powerful solution, it also repels and kills ticks before they can attach and mosquitoes before they can bite. Applied before the start of flea season, it helps keep your dog from becoming infested in the first place. Used year-round, it prevents fleas from over-wintering in your home to feast on your dog next season. Gentle enough for puppies as young as seven weeks and older, the flea control remains effective even after bathing, water immersion, or exposure to sunlight, without the need for re-application. This package includes four pre-measured doses for dogs weighing 21 to 55 pounds in easy-to-use applicator tubes. For safety, keep out of the reach of children, and read all warnings and instructions carefully.
