I feel for all of you...
Keeley's ears were the bain of my existance for awhile. It was tape and shave, shave and tape.
I noticed the biggest difference when I would shave the whole ear... Up and down, inside and out. I taped and taped but would only see a difference for a day or two...
Then when he turned 6 months I heard it was the deadline, and I stopped the taping. Then I heard that cottage cheese helped (
I don;t know why?) But I gave him some, and a little after that I noticed that they would stand up.
At one, now his ears poke 1/2 the time and flop the other. Especially if I keep them shaved. It is weird.
Good luck!!
The best way I found to shave is to wrap them (the yorkie) tightly in a towel, and then if you have someone there to help, have them give them some peanut butter to distract them. After the first few times, when they are a little more used to the noise and vibration, you can drop the PB and just wrap them tightly in a towel.
Hope that helps.
