I tried to glue my shelties ears at 6 months. (i actually got some Chinese surgical tape from a breeder here in eugene) And I kept them taped never having them un-taped for more then 2 hrs until she was 10 1/2 months. They just wouldn't go down at all. Taping them didn't even budge them at all. Her ears were straight up when we got her, I think the ear was just too hard by the time we tried. I love her cute little ears now, but at the time i just wanted her to look like all the sheltie things I was buying. lol. Hope the cocoa butter works for ya!
