The Top 5 Fastest Dog Breeds and Why They're Built for Speed

 

Speed is an essential trait in many dog breeds, particularly those originally bred for hunting or racing. The Greyhound, Saluki, Afghan Hound, Vizsla, and Whippet are among the fastest dogs in the world, each capable of incredible speeds due to their unique physical characteristics. From the Greyhound’s aerodynamic body and double-suspension gallop to the Saluki’s long-distance stamina, these breeds are built for speed through a combination of lean frames, powerful muscles, and exceptional agility. Learn what makes each of these dogs swift and how their natural speed has been shaped by centuries of selective breeding.
