The reason why dogs follow strangers

The reason why dogs follow strangers is because dogs are less alert and are easily tempted by strangers. Or it may be caused by the lack of deep relationship between the dog and the owner and the lack of loyalty of the dog. In daily life, you should spend more time with dogs, treat them well, and cultivate affection. You can also add some training to keep the dog from straying too far from its owner.
Dogs are actually just like children. Spending more time together will naturally develop feelings, and the dog will know who its owner is.
