Dogs recognize their owners by their noses. As a loyal partner of humans, dogs can easily recognize their owners. There are three ways for dogs to recognize their owners: seeing with their eyes, hearing with their ears, and smelling with their noses. A dog's nose is very sensitive. It can remember the owner's scent and can smell the owner's scent from a long distance, thereby distinguishing who is the owner and who is a stranger.

Performance of a dog recognizing its owner

1. When going out, the dog will follow its owner and will not let go. It will feel at ease when the owner is around. Some dogs even become aggressive.

2. When the dog is at home, the dog will stay with the owner and will not resist the owner's touch. Sometimes the dog will show a very humane expression when it makes a mistake.

3. Dogs will obey their owners after recognizing their owners. After a long period of training, some dogs can go to the toilet at fixed points and interact with their owners.

4. A dog will protect its owner after recognizing its owner. When the owner is in danger, the dog will rush towards the enemy regardless of its own safety. He will also look after the house when he is at home, and will make aggressive movements when a stranger breaks in.
