The best time for dog tail docking is usually within 1 to 7 days after birth. At this time, the nerves in the puppy's tail have not yet grown, and the tail bones are relatively fragile, so the surgery is less difficult and the dog's pain will be relatively small.

If you wait until the dog grows up and the nerves in the tail have grown, you can do tail docking surgery. The difficulty will increase and so will the dog's pain.
