I'm assuming they're cropped ears? or no? When pups go through teething, the cartilage in their previously normal ears can cause some wonkiness, cropped or not. If you want to glue their ears to be a proper rose shape, or tape them to stand for a crop, now is the time, assuming there are no stitches or big scabs on their ears. Please see the sticky under Health > Ear Crops. Best of luck, and please feel free to add a photo of the problem.
