A free-ranging dog is a dog that is not confined to a yard or house. Free-ranging dogs include street dogs, village dogs, stray dogs, feral dogs, etc., and may be owned or unowned. The global dog population is estimated to be 900 million and rising. Although it is said that the "dog is man's best friend" for the 17–24% of dogs that live as pets in the developed countries, in the developing world pet dogs are uncommon but there are many village, community or feral dogs.[1]

Stray dogs in the landfill.
It was introduced in 2 weeks after people when the wolves moves in and dogs are trying to move out. Ray Coppinger stated that dogs aren't good at little tasks like getting out of the house where they can't break a window, couldn't tear up things, and most of the dogs would sit and starve to death. One kind of canine is ideally suited to the new world, the stray dogs. Belonging to no one, they live on the outskirts of towns and are lean survival machines. Ray Coppinger stated that stray dogs are weigh about 20 pounds and designed to operate cheaply. He continues that they eat rotten food and been doing it for thousands of years. For the first few months after people, large populations of stray dogs live, eat, and battle for food at landfills and dumps and after that, survival becomes riskier.

Dingoes, a type of stray dogs released into the wilds of Australia in 2000 BC.
In 75 years after people, a kind of freedom has become the very essence of stray dogs. Once dependent on human leftovers, they've evolved back into the wild predators before domestication. Ray Coppinger stated there are already places in the world where they've evolved back into a wild animal like dingoes in Australia. Bought to Australia around 2000 BC as domesticated dogs, they were released into the outback and soon numbered in the hundreds of thousands. Ray Coppinger stated that the dingoes were doing perfectly well in the wild.
However, without humans to provide the stray dogs most of their food, the population were decimated, from more than 300 million to just a few million. Yet, they will endure because of an unique running ability that distinguishes them from every other creature in the animal kingdom. Ray Coppinger explains that the cheetah is the fastest animal in the world, but can only go 300 or 400 yards before becoming exhausted while the stray dogs can do miles and miles. He thinks that the stray dogs will be successfully survive.
