Evolution of dog food, domesticated dog

The first domesticated dog was found at a German site dated 14,000 B.C. Dogs were thought to work cooperatively with humans to locate and announce the position of prey.

There are 38 species in the dog family, Canidae, of which dogs and wolves only comprise a small percentage. Jackals, foxes, and zorros make up the majority. There is only one species of fully domesticated dog, Canis familiaris.

Because dogs have undergone a number of changes due to natural selection and have also changed drastically through artificial selection for hair colour, size, and temperament there are about 200 to 400 breeds worldwide.

Puppy rescue would not have been an isolated case but would have happened in many different groups of human hunters over our thousands of years of evolution and history. Selective breeding would have been automatic. Keeping a wolf that became overly aggressive towards the humans, or of little practical use, would have been both pointless and dangerous.

Only the remaining dogs, with desirable traits, would have been selected to breed. Eventually the traits of each group of tame Wolves would reflect the needs of the group of humans it lived with: it's size, colouring, senses and even the length of its coat or swimming ability reflecting the needs of the hunters and their environments.
