Dogs will recognize multiple owners. As long as the environment does not change, a dog will only recognize one owner in its life. When the owner abandons it or is re-adopted, as long as the owner is good to it, after a period of adaptation, it will recognize the new owner. After recognizing its owner, it is very attached to its owner, treats the owner as the most important person, is very obedient to the owner, and will not attack the owner.

Signs of a dog recognizing its owner:
1. Protecting food is a dog’s instinct. Once it recognizes its owner, it will not protect the owner’s food. When the dog eats , the owner can even touch its rice bowl.
2. After the dog recognizes its owner, it is very attached to the owner. It will act coquettishly and cutely, lick the owner's hand, and get close to the owner.
3. The owner has a strong awareness of protecting the owner. It will always follow the owner and focus on the owner. Once the owner is in danger, it will immediately protect the owner.
4. It is very obedient to its owner and allows it to be touched. When the owner calls it, it will run to the owner no matter what it is doing.
