Thanks Gunner, Lexy is my first dog to deal with the posting on, my other dobe from years ago was a rescue and already done. So I am by no means an expert. But with Lexus, I just made sure and this was stressed to me by the breeder to pull them upwards tauntly, not to hurt them, just to have them straight up before adhering them to the brace. I didn't use the tampoons and tape and stuff until the very end, when her brace was permenently off, and she had one ear that was a little stubborn. The brace I used kept them pulled upright.
Just keep them up, and when you have them down to retape, massage them upwards before retaping. Best of luck to your girl gunner!
