have you ever seen a team of horses harnessed together? ever notice their tails? like how they're almost non existent (all long hairs are bundled into a bun/twist). same thing applies to a team of dogs. rotties are big, strong animals, who crave stimulation like cart pulling, since it's in their DNA. tails are also docked to prevent injury not from livestock, but from the dogs they're attached to and the elements in which they work. it's more beneficial to a working dog to have their tails docked at 1-3 days old, before the nerves are formed and the bones hard. plz research prior to forming such a head strong opinion, as it's not very becoming
