How can a dog know his owner? Dogs can recognize their owner by identifying their owner's scent, facial features, sounds, etc.
Dogs have a strong sense of smell innately, which is dozens of times higher than that of humans. The olfactory cells of dogs are 60 times that of humans, and they can also identify odors with a concentration of 100 million times lower. In other words, it is not only more types of odors that people perceive, but also a wide range of odors that others perceive.
So you often see dogs smelling east and west on the road, which means exploring the world with your nose and discovering the world, smelling the fragrance to recognize people.
The second thing that allows the dog to distinguish his owner is hearing at once.
The ear structure of dogs is different from that of humans, and they can rotate and listen to signals like a small radar. In addition to identifying directions, dogs have 16 times hearing than humans, and their hearing sense is super strong, and the maximum range of hearing is about 400 times that of humans. You will find that you are far away, your dog can still hear your voice and distinguish your voice.
Finally, there is also the dog's memory. Although the degree is different, each dog is equivalent to the intelligence of a child, and will have a certain memory of the sounds they often hear and the familiar smells.
