What to do if a dog doesn’t recognize its owner:

1. The owner needs to give the dog some time and space, and wait until the dog relaxes its vigilance before starting to cultivate feelings and relationships with the dog. Dogs are more interactive.

2. Companionship. If a dog does not trust its owner enough, it will not recognize its owner. The owner should accompany the dog more and cultivate the relationship with the dog.

3. Correct the education method and do not educate the dog by beating and scolding.

4. Use snacks to tempt the dog. You can hold the snack with your hand and feed it to the dog to gain the dog's trust.

5. Take the puppy for a walk, and reward it appropriately if it behaves well. If it wants to go with a stranger, stop it directly. Over time, it will recognize that the owner will not follow strangers.

6. Give the dog a name. When walking or playing with the dog, you can often call it by name and feed it while calling its name. This can enhance the relationship between you.

7. The dog may not recognize its owner because he is deep in thought or in a daze. The owner calls the dog, but the dog ignores it.
