If there is no tendency to get up for 2 months, you need to do ear lifting assistance.
It is normal and gratifying to prick up your ears for about three months. But it was not until 4-5 months that the ears naturally stood up. Generally, the ears of dogs with thin ears are slowly erected.
If the whole ear is only half upright, don't worry; If the dog always folds forward and the ear is still upright after 5-6 months, it will be more troublesome, because the weakness of the cartilage at the root of the ear is not easy to correct in a short time.
