I believe all dog owners have experienced being licked by dogs, right? So why do dogs like to lick people so much? Actually, there is a reason for this. Do you want to know? Come and take a look!

1. Expressing love for the owner: A dog will not lick a stranger's hand easily, so the act of licking hands means that it recognizes you as its owner and expresses its affection for you.

2. Seeking attention: Dogs often run wildly or play with their tails. At this time, the dog is actually bored. When the owner approaches, the dog will seek attention by licking its hands and find someone to play with it.

3. Hungry: If the dog frequently licks the owner's hand that usually holds food when feeding, it is likely that the dog is hungry and thinks that it can get food by just licking this hand.

4. Habits: Some dogs have watched their mothers licking themselves since they were young. When they grow up, they have formed the habit of using licking to express their emotions.

5. Admit mistakes: Dogs sometimes lick their hands when they make mistakes. At this time, they know that they are wrong and that their owners are angry. Therefore, licking their hands is also a kind of comfort and hint to their owners.
