Is it okay to take the dog to the hotel without being found by the security guard?

I advise you not to bring it. Because your lovely pet may bring great inconvenience to other guests and even endanger the lives of other guests. Moreover, if your pet is in the hotel, it will bring great inconvenience to the cleaning staff to take urine in the room.

Dogs are domesticated by wolves. As early as the era of hunting and gathering, people have domesticated dogs as hunting assistants. So dogs are the earliest domesticated domestic animals. Dog bones have been found in Cishan, Wu 'an, Hebei, Peiligang, Xinzheng, Henan, Hemudu, Yuyao, Zhejiang, which proves that it has a long history of domestication. ?

The dog-shaped scorpion unearthed from Sanlihe River in Jiaoxian County, Shandong Province is vivid and lifelike, which makes us see the morphological characteristics of domestic dogs in Neolithic Age. The dog bones unearthed from Anbanpo site in Xi 'an, Shaanxi, have small skulls, protruding frontal bones, small cracked teeth and curved horizontal edge of mandible, which is quite different from that of North China wolves, indicating that the history of human domestication of dogs is indeed very early.

Canine ancestors

No one knows exactly when the first interaction between man and wolf took place. Some scientists think it may be 50,000 years ago, because it took wild wolves at least so long to show today's genetic differences. At that time, humans and wolves were distributed in many places on the earth's surface, and the evolution process may have occurred in several different areas.

Some scholars believe that wolves were domesticated from wild wolves to domestic animals for playing, hunting and housekeeping, that is, dogs, before 14000 years or even before 16000 years in Southeast Asia. ?

At present, all kinds of dogs in the world originated from wolves domesticated in the south of the Yangtze River valley in China about10.6 million years ago. Peter Sa Flening, a scientist from the Royal Swedish Institute of Technology, confirmed the origin, location and time of dogs.
