Greyhounds repeatedly top the list of fastest dog breeds, often maxing out at 45 mph speeds thanks to their slender bodies and flexible spines. Greyhound Brett Lee set the record for the fastest 100-meter spring with a time of 5.53 in 2001 (Usain Bolt would swoon), but the breed boasts serious endurance and can sustain 35 mph speeds for more than 7 miles. When they’re not breaking records, you can find greyhounds affectionately doting on their loved ones — they’re known for their friendly demeanors.
Saluki These smooth-coated dogs, once prized by nomadic tribes for their ability to chase down game, are now domesticated. However, salukis are still fast and give greyhounds a run for their money. This breed can reach 43-mile-per-hour speeds. Salukis remain natural chasers, so you’ll want to keep yours on a leash. While they can be challenging to train, salukis are gentle and good with kids and other dogs.
Afghan hound
Afghan hounds can run as fast as about 40 mph, which served them well when chasing down large animals as hunting companions in Afghanistan’s cold mountains (their coats helped, too). With U.S. families today, Afghan hounds strike a balance between being independent but loyal — the best of both worlds.
Doberman pinscher
Doberman pinschers are among the most protective dog breeds. Their speed helps them keep their favorite humans safe (likely from evil leaves blowing). Dobermans can reach speeds of around 32 mph. Though they look imposing, Dobermans are gentle giants known for being wonderful with small children.
