Dogs given by others will recognize their owners. A dog is very loyal to its owner and will always remember the original owner after giving it away. However, as long as the new owner is friendly and patient with it, it will recognize its owner again. It's just that the emotion towards the second master will change, losing absolute trust and becoming independent and obedient. As long as you prepare food on time, spend more time with the dog and interact with it, the dog is willing to get close to its owner, which means it recognizes the owner.

Signs of a dog recognizing its owner:

1. The dog will often stick to its owner, and the dog will surround him wherever the owner goes.

2. The dog will respond to the instructions given by the owner to a certain extent. For example, if the owner calls it, the dog will naturally run to the owner.

3. Dogs will protect their owners. If a dog sees other dogs approaching its owner, or other people bullying its owner, it will be aggressive to other dogs or people.
