My GSD is 9 months old. I started doing breath right strips and mole skin on her right ear at 8 months as it was having difficulty standing up at rest. The mole skin/ strips fall off and she will sometimes have the ear stand up for a whole day or 2 and then I have to reapply. When we are playing frisbee, on a walk or generally anything exciting... She is able to get both ears up. The base of the ear is strong. When I feel the right ear I do feel a thinner portion where it's been creased....I don't know if I should give up or is it a good sign that she can get both ears up when excited?
