Generally, dogs have tails. Only genetic mutations or teratogenic factors cause dogs to be born without tails. These tailless dogs are no different from other dogs except for their tails. Most of the common tailless dogs nowadays are caused by artificial tail docking, such as: Corgi, Doberman, Rottweiler, Schnauzer, etc.

Tips:

Generally, more small and medium-sized dogs have their tails docked, some for appearance, and some for work reasons, so owners will choose to dock their tails. . Usually some puppies will have their tails docked 2-5 days after birth, because if the tail is docked too late, it will make it difficult for the wound to heal, leading to wound infection.
