Zymox Water Resistant Topical Spray utilizes the Patented LP3 Enzyme System in a water-resistant antimicrobial spray that safely helps treat skin and hoof infections. The addition of the biofilm reducer to the LP3 Enzyme System allows greater penetration and shorter treatment time against resistant microorganisms. The water resistant property provides optimal residual effectiveness for animals that spend the majority of their time outdoors. Safe for use on all hoofed animals, yet gentle enough for companion pets as well. Contains no Hydrocortisone.
