As its name implies, Dual Action Gel accomplishes two things at once: accelerating healing by helping to eliminate harmful bacteria while repelling flies and insects that are naturally drawn to open wounds. Our easy-to-apply gel forms a “second skin” barrier over the wound to allow complete healing while keeping pests away without the need for bandages or coverings. And it does so without the use of harmful chemicals! Our nontoxic, antibiotic-, and steroid-free formula has no odor and will never sting or burn your pet when applied.
