We just took in a 22 month red male, ( he needed a new home due to family moving) although this is not are first doberman, I was wondering if any one could answer a question. His ears are cropped but one does not post, at this age can we try to correct this? Sorry I don't have a picture yet. We do have the knowledge to tape them but not sure if reposting will work at this age. Thanks for any info.
