A dog only recognizes its owner. Dogs are very loyal animals. They usually recognize their owners when they are three months old. Dogs can recognize many owners in their lifetime, but they can only recognize one owner at a time. Therefore, it can only recognize its owner. It will not regard the owner's family as its owner, but it will be very friendly to the owner's family and will not harm the owner's family.

Methods to train a dog to recognize its owner

1. Feed and water the dog in person every day. Dogs are very spiritual and will naturally understand how good their owners are to them, and will no longer be wary of their owners, laying a solid foundation for recognizing their owners.

2. Take your dog for a walk often. Dogs like to be walked very much. If you increase the interaction with the dog when taking it for a walk, it will become familiar with the owner, which will help it recognize the owner.

3. Give the dog a name and call its name often. Over time, the dog will form a conditioned reflex to remember its own name. When the owner calls it, it will immediately appear next to the owner, making it easier to recognize the owner.
