It sure seems like there are more dog breeds living around the world than most people can count. But believe it or not, there was a time in which there were even more.

These long-gone breeds once ran around with our ancestors, keeping them company just like our dogs do today. But each of these breeds are now extinct, with practically no hope of ever coming back.
