It is no secret that dogs a fast. Even the tiniest of dog breeds show incredible feats of speed when called for, but there are some dog breeds which are head and shoulders above the rest, and can reach truly extraordinary speeds that can leave even the fastest human in their dust.

Canine phsyology is particularly developed for speed, and certain breeds are even more capable because of this makeup.

  • Dogs have a much higher metabolism than humans, which means they are able to process more oxygen, and pump blood much faster.
  • Dogs have feet which are designed to grip the ground.
  • Dogs have a double-suspension gallop, using their spine, and strong abdominal muscles to aid their legs in sprinting along.

Some breeds have even more working for them. For example, the Greyhound, aside from their muscular bodies, have aerodynamic heads which aids them in gaining the extreme speeds they are capable of. Another thing that makes certain breeds more capable is the size of their hearts compared to their body size, which enables them to pump massive amounts of blood at full speed.

Greyhound: Clocked at 45 miles per hour, the Greyhound is the fastest of all dog breeds. Its aerodynamic shape and highly muscular body allows the Greyhound to move considerably faster than the next fastest dog breed.

Saluki: The Saluki, hailing from ancient Persia, is the second fastest dog breed. It was developed as a hunting dog, and can do its job admirably. It can reach speeds of up to 43 miles per hour—not quite as fast as a Greyhound, but pretty close.
