Innovet Pet Products' PurOtic all-natural ear cleanser features a patented silicone applicator designed to deliver cleanser to the inner ear without causing pet discomfort, the company states. Users squeeze the trigger to dispense at low pressure a small amount of ear cleaner through the flexible dispenser. The cleansing wash, which contains essential oils with antiseptic properties and natural fragrances, uses a highly refined emulsifier that is superior at breaking up wax, the company adds. Available in 4- and 8-oz. sizes.
