Clone a dog to recognize its owner. Although cloned dogs have no memory. But because it has the same genes as the original dog cells, it will have some simple cell memory. In other words, the cloned dog will not naturally remember the owner, but will have a sense of familiarity with the owner. When you return to the owner's house for the first time, you will feel familiar when you see the original dog's toys, food bowl, etc.

How a dog recognizes its owner:

1. Listen to the owner. 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.

2. Like to stick to the owner. Dogs will often cling to their owners, and the dogs will surround them wherever their owners go.

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