Optima Ear flush for dogs ears that require a deeper clean. It works by dehydrating the inner ear where bacteria can build. Usage Guidance: Pull the dogs ear slightly outwards towards you to open up the canal. Tip the dogs head to one side and fill the whole ear canal with the flush. Hold the dogs head in position for 30 seconds whilst massaging the bulla area at the base of the ear. To ensure the ear is flushed out after administering allow the dog to shake its head. Then get a clean towel and clean the ear area for excess fluid and debris. Do not apply to broken skin. Before applying make sure that the dog’s ear drum is not perforated. Allow the product to sit for 20 to 30 minutes before using so it warms to room temperature. Use as a 1 time flush but if needed repeat in 7 days. Consult your veterinarian before attempting home treatment. Contains: Isopropanol, Dihydrogen Dioxide Use within 18 months of opening. Store in a cool, dry place. Net quantity: 60ml
