Please continue posting. Natural ears are fine, but if the ears have been cropped they should be posted until standing. Just curious, but why did you buy a puppy that was cropped if you wanted natural ears? After cropping the ear leather can curl and flop back overt the head if not trained to stand.
Also, read your contract -- some breeders require cropped ears to stand for guarantees to apply.
