Why do dogs like to lick human ears? Dogs like to lick human ears may be because of one of the following reasons:
1. Social behavior: Dogs express intimacy and social behavior by licking human ears. In the eyes of dogs, licking human ears is an intimate act that can enhance relationships with humans.
2. Body odor perception: Dogs have a very sensitive sense of smell, and they can perceive human body odor by smelling and licking their ears. This is a way for dogs to know and understand people.
3. Cleaning behavior: Dogs sometimes treat human ears as part of themselves to clean them. This is because dogs are born with a strong cleaning instinct, and they lick themselves and other animals’ hair and skin to keep them clean.
It should be noted that there are bacteria in the dog's mouth, so it is not recommended to let the dog lick human ears. If a dog licks a person's ears frequently, it can be stopped by training and instructions. At the same time, pay attention to maintaining oral hygiene of the dog and take it to the veterinary examination regularly.
