MicroSpore Leave-On Lotion is a non-oily topical lotion made for dogs, cats and horses with skin conditions that respond to chlorhexidine and ketoconazole. The formula combines 2.3 percent chlorhexidine, part free-form and part encapsulated, with 1 percent ketoconazole, along with a natural biopolymer that forms a barrier on skin and hair. This barrier is designed to reduce adhesion of bacteria and yeast on the skin surface and to help protect against environmental irritation. The lotion is applied to a wet hair coat and massaged into the skin, and it leaves no oily or sticky residue once absorbed. Each unit in this listing is a case of twelve bottles for multi-pet households or practices that go through the lotion regularly. It is intended for external use only, and a licensed veterinarian should be consulted regarding the frequency and duration of use for a given animal.
