I think you're a GENIUS!
This is a tip I might definitely try. My 12 week old has ears juuuust trying to stand, and one cocks up higher than the other....SO CUTE! But since her mom's ears tend to flop most of the time, I sort of wonder what hers will do.
I love both standing AND floppy ears, and she is a VERY active little girl

, so I'd already pretty much decided that messing with taping wasn't going to be worth the frustration for either one of us. But this, this I would try.
Thanks for the tip!
