Do dogs often identify their owner s voice?

Mammals have high similarities in the human internal organs and nervous system structure. Dogs also have human brains. Like people, their human brains are also responsible for solving external light, sound, touch and other information. Among them, visual effect information is the key method for mammals to obtain external information. There is much less sound information, and less touch and other information will be less and less.

The dog's ability to identify its owner's voice in a noisy natural environment is attributed to its alert taste and auditory system capabilities. Compared with humans, the dog's strong taste and visual effects are similar to that of a superpower.

The strong ability of dogs' tastes reflects two levels; first, they are extremely sensitive to taste. Second, it can identify different flavors. Dogs have strong taste abilities that can identify two million different flavors. In addition, they can also identify the type they need to find from various mixed tastes, and even achieve analytical level, especially the level of sensitivity to acid and alkaline tastes, which can achieve tens of thousands of times that of people. The auditory system of dogs is also unmatched by people. The longest distance of hearing sounds is 400 times that of people. When you sleep at night, you can clearly hear all the sounds within a range of half a kilometer, and you can also identify the origin and direction of the sounds. It is even more powerful than the knights with strong internal strength in ancient martial arts novels.

Generally, the dogs raised at home and they say everything, and their habitual behaviors will leave a more unforgettable memory for the dog, so they can identify their owners in many sounds. This whole process is the same as people recognize their family’s voice.

Therefore, in the noisy natural environment, dogs can also identify their owner's voice and understand their owner's return home.
