There are many idioms to describe a person who is very naughty, such as naughty, shameless, shameless, begging for nothing, unreasonable and so on. This kind of person is always ahead of others and complains that he can't live well and is just too lazy to do anything.

To be honest, these people are not as diligent as dogs. The dogs even take their owners out for walks every day. When walking dogs outside, they will not only pay attention to the surrounding environment and things, but also be curious about what the owner is doing now and whether he has eaten anything behind his back. Therefore, when walking and looking back at the owner, it may be simply because you are curious about what the owner is doing.
