How Fast Is Greyhound?

Bred for 5,000 years purely for speed, greyhounds reach 70+ km/h and sustain it longer than a cheetah. Their double-suspension gallop, flexible spine and 40% muscle mass make them the most efficient pure speed machine in dog form.

A greyhound would beat a cheetah in a 500-metre race — the cheetah would overheat and stop first.
