Can Shelties still have their ears cropped at 1 year old? Shelties can still have their ears cropped at 1 year old, but the nerves in the dog’s ears are more developed at this time and it can be more painful and not easy to recover. The best time to crop your Sheltie’s ears is when they are 3-4 months old (100 days to 145 days). It is recommended to find a professional to perform the ear clipping procedure. The best time to establish the ear is between 100-145 days. At this time the large blood vessels in the ear have not formed and healing is 1 week. If it is more than 4 months old, the ear will bleed a lot and the shape of the ear will change easily. It also takes a long time for the ear to heal.
