K9 Advantix II Flea & Tick Treatment for Small Dogs is scientifically designed to minimize the threat of fleas, ticks, mosquitoes, and other pests.

When fleas, ticks, lice, stable flies and other pests come into contact with this solution, they’re immediately paralyzed. Fleas and lice will die off almost instantly.
