What does it mean when a dog licks its owner?

The reasons why dogs lick their owners:
1. When a dog is bored and wants its owner to play with it, it will lick its owner non-stop.
2. When a dog is hungry or thirsty, it will lick its owner to signal the owner to feed it.
3. If the dog suddenly becomes clingy and keeps licking its owner, it may be sick and asking for help from its owner.
4. Dogs often express their thoughts through body movements. Licking the owner is expressing love to the owner, which means that it likes the owner very much.
5. When the owner is in a bad mood, the dog will keep licking the owner to comfort the owner.
6. If the puppy keeps licking its owner, it may lack a sense of security and needs to gain a sense of security by constantly licking its owner.
7. If the owner has just eaten a snack and the residual food smell is on the body, the dog will also lick the owner.
8. Dogs are very possessive. Sometimes licking their owners is a mark, leaving the smell on their owners and declaring their sovereignty.
9. When a dog does something wrong, it will lick its owner to beg for forgiveness.
