A Greyhound, which is the fastest dog breed, runs at full speed.

How Fast Can Dogs Run?

If you’ve ever chased your dog through the yard or watched them bound through the park at a full sprint, you’d probably agree that dogs can really move. While speed varies from breed to breed, the average dog can run at a pace of between 15 and 20 miles per hour over short distances.

Why Are Dogs Such Great Runners?

A dog’s prowess on the track starts at ground level. Paw pads and nails provide the power to explode into a sprint, as well as the traction necessary to change direction and gait quickly. At top speed, especially fast dogs break into what’s known as a double-suspension gait. This is the same gait you’ll see from a racehorse, which is all four limbs leaving the ground at the same time. It’s especially common among dogs with lean builds, deep chests, and long legs.

How Fast Can Greyhounds Run?

Many breeds are speed demons, but Greyhounds are definitely the top dogs. Greyhounds only need six strides to reach their full speed of around 45 miles per hour. Among mammals, only cheetahs are capable of accelerating faster and some studies suggest Greyhounds would win in a head-to-head competition.

What makes Greyhounds so fast?

In addition to the speed-boosting features noted above, Greyhounds have other genetic gifts that make them so fast. Most notably, the breed’s heart is huge in relation to the rest of its body. The human heart accounts for about .5% of a person’s body weight and the average dog’s heart accounts for .77% of its weight. Depending on their weight, a Greyhound’s heart could account for nearly as much as 1.75%. Beating five times per second, it can circulate all of the blood in the dog’s body multiple times even during a brief race. Greyhounds are also powered by exceptionally long, slender legs and flexible spines.
