As a breeder, I can tell you that they can come up on their own at 6 weeks. Mine are all usually up by 8 weeks. The breeder needs to start trimming the hair off the ears at even 3 weeks old. You can tape ears. You have to do it right though. You can google it to find some good tips. I also feed lowfat cottage cheese to encourage the ears to go up, it can work wonders
A teaspoon a day.
