In urban development, not only human beings, but also a large number of stray animals, some of them natural microbes, only inhabited by humans, only to steal and others abandoned by humans, who were used as commodities and are now living alone.
Since many small pets themselves are not species able to survive in the suburbs, they have been abandoned in a terrible way, such as many hairy dogs whose hair is constricted after a period of vagrancy, whose stains are too heavy to see, which can cause illness or fissure, and the death of their heads.
But this stray dog, who still has confidence in humans, can also act unexpectedly when it encounters difficulties, such as when a stray dog actively walks into a shop by the roadside, and the owner gives it a bowl of water, but he does not want to drink it. He just sits with his own front paws and doesn't shake his tail, he doesn't scream. He realizes that it's a frontal claw wound before he calls for help.
