I've become a big fan of vetericyn, on any of my dogs cuts, and scrapes.
I've seen where people use a feminine napkin on the inside of the ear flap, and then wrap the ear. Then wrap the ear to the dogs head/neck.you would need non stick gauze, and coach wrap. If you don't put a cone of shame on too, I would think most dogs would try to get it off.
Last you would need to make sure you don't wrap the ear to tight, and risk cutting off the circulation.
II've also seen some where the used a cut to length tolite paper roll on the inside of the ear flap, and wrapped like described above.
I've heard ears, and tails are the hardest to get to heal. So I wish you lots of luck.
