American Humane Association does not have an official position on the issue of tail docking; however, American Humane Association does oppose cosmetic surgery on animals when performed solely for the convenience of the caregiver.
Tail docking typically is performed when a puppy is three to five days old. Anesthesia is not usually used, causing the puppy a great deal of pain. American Humane Association opposes this cosmetic procedure unless it is medically necessary, as determined by a licensed veterinarian.
