A convenient monthly topical application that kills and repels fleas, ticks and mosquitoes, kills lice and repels biting flies. It’s specifically formulated for dogs with imidacloprid, permethrin, and pyriproxyfen for broad-spectrum protection against these ectoparasites that can transmit diseases to your patients. And because it kills through contact, there’s no biting required.
