When Belle was at the breeders, her ears went up at teething and the breeder did not do anything about them.. she said I could "work on them" but of course, we know that when the ears are up, unless they are braced, taped, or glued, they are set. In any event, I have been using speed sew to keep them down but one of them keeps coming undone.. I read this morning about something called "blu-tack" which is an adhesive, and wondered if anyone has tried it for their shelties..
