GERMAN SHEPHERDS ears usually stand naturally by 4-5 months old. They will cross, go outwards, one up and one down, beforehand. If they are extra large or heavy they may struggle to go up. Or if they are teething early, it may slow the process. If I get concerned about an ear or two, I go to a vet, that specializes in ear cropping and get them taped up for a week or two. I have done that a few times with great success. But usually they go up on their own.
