The tail of a Corgi does not necessarily have to be broken. The Corgi's tail is very important to them. The Corgi's job is to herd cattle. In order to prevent the Corgi's tail from being stepped on by the cows, the herder chose to dock the Corgi's tail. Now no one regards the Corgi as a cattle dog anymore. Once used, tail docking is no longer necessary.

The reasons why humans dock the tails of Corgis:

1. Following the trend of tail docking. Many people dock the tails of Corgis, which has formed a breeding habit. Especially Corgis participating in competitions need to have their tails docked.

2. Show your peach butt. Many people think that corgis with their tails docked can show off their cute big butts and look better when walking.

3. Reduce risks. Corgis are small in stature and cannot withstand danger. When Corgis are afraid and surrendered, they will tuck their tails. In order to prevent other dogs from finding out the details, the dog owner has no choice but to cut off the Corgis' tails.

4. Work needs. The Corgi itself has a long, fluffy tail, which is inconvenient for herding cattle. It is easy for the tail to be stepped on by the cattle, resulting in injury or even fracture of the tail.
