How many km/h can a dog run is a question that many people are interested in. In this article, let's learn about the speed of dogs !
When we chase our dogs to retrieve a stolen shoe or to put them in a kennel for the night, they seem to be trying to qualify for the Indianapolis 500. But most of the world's fastest dog breeds aren't just trying to elude us, they're also specifically bred to hunt, track pests, or test their ability to run competitively.
The fastest dog breeds on this list easily average 30 to 40 miles per hour, and six of the seven fastest breeds are sighthounds, using their keen eyes and sprinting ability to hunt or race, says Jerry Klein, DVM, chief veterinary officer for the American Kennel Club (AKC). Most of the world's fastest dogs share the same traits: long legs, lean bodies, deep chests to allow for more lung room, and slim waists.
Here are the fastest dog breeds in the world today
