Greyhounds are so much more than the world's fastest dog, though they hold that title with pride. They are also the most ancient purebred dog, some day dating back over 5000 years, while others put it closer to 2500 or so.
A Greyhound is spoken of in the Odyssey and both Chaucer and Shakespeare wrote of greyhounds.
Every single Greyhound alive traces its pedigree back to one dog, King Cob, who was born in England in 1839. Talk about THE Greyhound Baby Daddy!
Let's go back to just how FAST they are. A Greyhound can run up to 45mph, getting too 35 mph in just three strides! The fastest racehorse was clocked at 43 mph. Usain Bolt, we've got your next challenge!
