A one-year-old dog will recognize its new owner. The key is that the new owner treats it well. Dogs are very humane and will recognize anyone who treats them well, but it takes some time to get familiar with them. After all, dogs still have a sense of distance when they first come into contact with strangers. During the period when the dog recognizes its owner, it is recommended to feed it in person and stay with the dog more so that the dog can become familiar with your own scent. After the dog recognizes you, you can train it.

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.
