Why are the lines on each dog's nose unique?

If we carefully observe the dog's nose, we will find many lines, which are actually very similar to our fingerprints. The line of each dog's nose is unique, and it is impossible for dogs with the same line to appear.

So Mao Mao thinks that if we can identify the nose lines of dogs in the future, can we reduce the problem of many dogs getting lost? So no one will be sad because the dog is lost. The most prominent feature of dogs is their sense of smell. Dogs usually smell food when eating, judge the quality of food by smell and decide whether to eat. Moreover, our bodies will have a unique smell, so dogs can detect our arrival from far away every time and run out to get ready.

For dogs, our world is slow, and some actions we make are actually slow motion for dogs. Our 1 sec is four seconds for dogs, so dogs can accurately catch thrown food or toys.

Studies have shown that when dogs see their owners crying or sad, their companions will cry in their brains, thus feeling their owners' hearts. Jin Mao, a warm man recognized by the dog industry, will come forward to comfort his master when he is sad and rub his head against our legs to express comfort. Therefore, the emergence of cured dogs may come from this.
