Dogs have become one of the best pet companions of human beings. They are lovely and kind, and their loyalty is deeply imprinted in the hearts of many people.

Dogs and humans began to live together about 14000 years ago. At that time, dogs were relatively independent species, and they did not rely strongly on people. However, several factors narrowed the distance between dogs and people.

At that time, human beings had started hunting. People hunted to get the food they needed. It is in the process of hunting that people gradually find that dogs can provide advantages to the hunting process. Both the dog's sensitive sense of smell and hearing, as well as the protection of hunting achievements, proved that dogs were becoming more and more important to people's lives.

Fortunately, dogs and people seem to have a natural affinity. Dogs like to be with people, and people are willing to live with dogs. Over time, this affinity has also contributed to the relationship between humans and dogs today.

In modern society, the family is a dog’s living group. It is dog's nature to trust the leader of the group and strive for the interests of the group. This explains why dogs are so loyal to humans. Getting close to people also improves the way dogs communicate with people. Studies have shown that dogs have developed a strong ability to read human language and body cues. This allows dogs to begin to understand human feelings and respond to them.

The owner's breath can stimulate some positive emotions in the dog's brain, and they are also good at enjoying this emotion. The dog's ability of intimacy is indeed unique in the animal kingdom. Even though the cat has entered the human life, you can't deny that the dog's feelings for people are comparable to those of the cat.

Dogs and humans have lived together for so many years and have established a special relationship. Humans feed dogs in exchange for protection and companionship. After thousands of years of development, dogs have become one of the closest pets to humans.
