Dogs, in their current form and as we know them today, are believed to have evolved from wolves. Through a process of domestication that began as far back as an estimated 15,000 years ago, dogs slowly became separate from their wild wolf ancestors. So, it’s highly likely that dogs as a species would have existed even without humans.
