Yes, most Corgis are born with a tail. Some Corgis are born with full tails while others may be born with naturally short
bobtails depending on the type of Corgi.
Cardigan Welsh Corgis typically have long, bushy tails that they carry low. The AKC Breed standards call for
Pembroke Corgis tails to be docked (the practice of surgically removing a portion of the tail) if born with one that is considered “too long” according to breed standards, but
resistance to docking practices is growing, and tail docking is illegal or restricted in many places, as it is medically unnecessary.
