Question: when do pomchi ears stand up?
Answer: Puppy Ears that Do Not Stand Erect However, during the teething stage (4 or 5 months to 8 to 9 months or so), the ears may be affected; they may stand at some times, but flop a bit at others. In these cases, often the muscles will strengthen, and they will stand erect for good usually by the 12 month mark.
