A dog can recognize several owners. The dog can only recognize one owner at the same time, but after the dog leaves the original owner, if the new owner treats the dog well, the dog will recognize the owner again, but this process is very painful for the dog.

Notes on letting dogs recognize their owners:

1. When dealing with dogs, you should treat them with a gentle attitude and let them treat their owners Generate dependence and trust, and don't be too harsh. This will leave a psychological shadow on the dog and make it fearful of the owner.

2. The owner should cultivate the owner’s leadership status through diet. The owner can feed the dog at a fixed time every day, so that it knows that its food is distributed by the owner, so as to understand the relationship between master and servant.

3. Training is a necessary means to make the dog recognize its owner. Training can cultivate the dog's obedience. But training is also a step-by-step process. Start with simple training, and the training time every day should not be too long.
