I'm pretty confident with posting ears, but Gunner's are giving me major issues lately. I use the tampon method, and can't keep the bottom from popping out of his ear when he shakes his head or plays. I do the tape so that it's sticky and sticks to the ear, and I tape around the base really well..it doesn't matter. A day or so and it's popping out and i have to start all over. Any ideas how to correct this?
