Within how many days we need to dock a Rottweiler Tail..???
Docking tails on any breed should be done within a maximum of 3 days after birth. 2 days is usually fine.
Make sure it’s done cleanly to prevent infection too, a veterinarian is usually the best person to dock tails and remove dew-claws (which can be done at the same time).
Hope this helps. Good luck.
