Solutions to Corgi not sleeping at night:

1. You can solve the problem by playing games with it during the day to consume Corgi's energy.

2. You can also place it next to its owner to sleep, or place it in a small space to give it a sense of security and let it sleep.

The reasons why Corgis don’t sleep at night:

1. If it is a Corgi puppy that has just entered the house, it is probably because it is very concerned about the environment and its family. Being unfamiliar, feeling scared because of not adapting, and not sleeping.

2. If the Corgi is suffering from a disease, he may not be able to sleep due to physical pain.

3. Because the Corgi has not developed good work and rest habits since he was a child, the Corgi does not sleep on time at night.
