I use the Breathe Right Nasal strips (large size). These can be found at most drugstores and places like Walmart. Trim the hair on the inside of the ear using a #30 or #40 blade in your clippers. 2.Take a large nasal strip, remove the backing and coat the adhesive side with Skin Bond. Allow it to sit for a couple of minutes in order for the glue to firm up a little. Stick the nasal strip vertically, starting at the very tip of the ear and in the middle, allowing it to go as far down the inside of the ear flap as the strip will permit. (there is no bending it over or folding it around the ear; just one strip on the inside of the ear from the tip down). Depending on the length of the dog´s ears you may need to go one size larger or smaller in addition to your first strip. Change the strips every 2 – 3 days, when they fall off or are loosened or scratched off, whatever comes first.
