I used Speed Sew to glue my Shelties Ears down.
Her name is Heartstrings Heirloom and her ears are supposed to be folded over for the shows, but when tape won’t stick to the ears then we just apply a little Speed Sew to the hair and glue the ear down in a natural curve.
Comes right out with a little glue remover and doesn’t damage the ear. Tape makes the ear pink and sometimes tears the skin, not Speed Sew.
