The reasons why Corgi needs to cut his tail:

1. Work needs. The Corgi is a cattle dog that helps herders herd cattle. Docking the tail of the Corgi prevents the Corgi from being trampled by cattle when herding cattle.

2. Avoid fractures. If a Corgi's tail is not docked when it is a puppy, its tail will be easily injured and may even be broken in severe cases, endangering the dog's life.

3. Highly ornamental. This belongs to modern people's aesthetic point of view. It is believed that corgis look better without tails, and tail docking can help improve the ornamental value.

4. Easy to take care of. Corgi's big tail is always stained with excrement, so it is easy to take care of it after docking it.

CorgiNotes on tail docking:

1. Best time. The best time for tail docking is 4-10 days after birth. If you miss the best time, do not blindly dock the tail.

2. Anesthesia is strictly prohibited. Tail docking does not require anesthesia. Instead, a rubber band is used to block blood circulation, causing the tail to gradually lose blood and eventually fall off. If you are allergic to corgi anesthesia, blind anesthesia will lead to death directly.

3. Rubber band position. It should fall where the tail and back fit together to avoid damaging the anus.
