Years ago I raised Great Danes, and though the ear crop on a Corso is much shorter, you may be able to use this method. Take a tampon, the cotton inside part and place it inside the ear and put the tape around it backwards, so the sticky is on the outside. This is called back wrapping. Then add more tape as a bridge from the tip of one ear to the other. The tampons are cotton and much softer on the dogs ears.
Hope this helps.
