Cheetah vs Greyhound - World's Fastest Dog In Super Slow Motion

What do greyhounds and Cheetahs have in common? With some amazing slow motion footage of a greyhound running, the crew at Earth Unplugged share some interesting facts about what makes greyhounds so fast and how they differ from the fastest animal on earth.

The greyhound is the fastest canine in the world and is the second-fastest land animal after the Cheetah. They can run with a peak speed of about 43 mph (vs a Cheetah's 75 mph).(Source)

“Cheetahs and greyhounds are known to use a rotary gallop and physically they are remarkably similar, yet there is this bewitching difference in maximum speed of almost a factor of two,” said study co-author Alan Wilson from the Royal Veterinary College of London, in a statement.

To compare the two animals, the researchers first enticed the big cats living in the ZSL Whipsnade Zoo, UK, and the Ann van Dyk Cheetah Centre, South Africa to run after bait and across force plates buried in the ground while filming the chase at 1,000 frames per second.

The researchers also analyzed the length of time that each animal’s foot remained in contact with the ground — known as the stance time. For some of the cheetah’s limbs it was longer than the greyhounds, and the team suspects that this may be another factor that contributes to the wild cheetah’s record performance. Wilson explained that by increasing the stance time, the animal put less strain on the animals legs and “’[with] a longer stance time the cheetah will get to the limiting load at higher speed than the greyhound.”

    Amazing speeds from both of them.

  2. just breathtaking!

    one thought about why the cheetah is nearly twice as fast as the dog - could it be, perhaps, that the cheetah is so much larger?

    cheetah - 72" average length, 26-37" tall at the shoulder, average weight about 100lbs
    greyhound - under 4ft long, 25 - 30" tall at the shoulder, average weight about 70lbs
