We did all those things, took her to the groomer shaved her ears like suggested, taped them several days on several days off as directed when she was about 4/5 mo old and they never did stand up. To me her ears seem large for her size even though she is a purebred. She hated it and fought us all the way.....We just gave up and decided to love her ears floppy! If I don't put her bangs in a bow or clip people always thing she is a Lhasa Apso or some other breed. She is also very large at 11lbs. But we love her just the same. Here is her picture with Oliver our cat.
