Dogs are known for their loyalty, intelligence, and companionship—but some breeds are also built for breathtaking speed. Whether they were bred for hunting, racing, or herding, these dogs can sprint with incredible grace and power. If you’ve ever wondered which dog can outrun the rest, you’re in the right place. In this article, we’ll explore the five fastest dog breeds in the world, what makes them so swift, and how their physical traits give them the edge in the race.
These high-speed canines aren’t just fast—they’re also intelligent, athletic, and full of energy. Let’s get to know the top contenders in the canine speed Olympics.
1. Greyhound
Top Speed: 45 mph (72 km/h)
Height: 27 to 30 inches
Weight: 60 to 70 pounds
The undisputed champion of canine speed, the Greyhound was bred for coursing game and later became the star of the dog racing world. These dogs are lean, aerodynamic, and muscular, with long legs and deep chests that allow for powerful strides.
Why they’re fast:
- Unique “double-suspension gallop”
- Low body fat and long limbs
- Strong cardiovascular system
Despite their speed, Greyhounds are known as “couch potatoes” and are incredibly calm and affectionate at home. They make wonderful pets for families who can provide short bursts of exercise.
2. Saluki
Top Speed: 42 mph (68 km/h)
Height: 23 to 28 inches
Weight: 35 to 65 pounds
Nicknamed the “Royal Dog of Egypt,” the Saluki is one of the oldest known dog breeds, revered for both its speed and elegance. Originally used by nomads to chase down gazelles in the desert, the Saluki combines long legs with a lithe frame.
Why they’re fast:
- Slim, aerodynamic body
- Deep chest for lung expansion
- Strong but lightweight muscles
Salukis are sensitive, loyal, and independent. They enjoy quiet environments and form strong bonds with their owners.
3. Afghan Hound
Top Speed: 40 mph (64 km/h)
Height: 25 to 29 inches
Weight: 50 to 60 pounds
With its flowing coat and aristocratic demeanor, the Afghan Hound might not look like a sprinter at first glance. But don’t be fooled—these dogs are extremely agile and fast, with a powerful stride that makes them excellent chasers.
Why they’re fast:
- Strong hindquarters
- High hip placement for long strides
- Lightweight frame with hidden muscle
Afghans are independent thinkers and may be aloof with strangers. They require regular grooming and enjoy running in open spaces.
4. Vizsla
Top Speed: 40 mph (64 km/h)
Height: 21 to 24 inches
Weight: 45 to 65 pounds
The Hungarian Vizsla is an all-around athlete, originally bred for hunting and retrieving. Their muscular build, endurance, and speed make them one of the fastest breeds, particularly over long distances.
Why they’re fast:
- Balanced build of speed and stamina
- Long, lean legs
- Strong cardiovascular system
Vizslas are energetic, affectionate, and thrive on human interaction. They do best with active owners who enjoy outdoor adventures.
5. Jack Russell Terrier
Top Speed: 38 mph (61 km/h)
Height: 10 to 15 inches
Weight: 13 to 17 pounds
Don’t let their small size fool you—Jack Russell Terriers are compact speedsters with explosive acceleration. Originally bred for fox hunting, these dogs are known for their agility, determination, and stamina.
Why they’re fast:
- High energy-to-weight ratio
- Strong, muscular hind legs
- Agile and quick reflexes
Jack Russells are fearless and intelligent. They require regular mental and physical stimulation to prevent boredom.
What Makes a Dog Fast?
Several physical and behavioral traits contribute to canine speed:
- Muscle Composition: Fast-twitch muscle fibers give dogs explosive power.
- Long Limbs: Longer legs provide more stride length.
- Lightweight Build: A lean body helps with aerodynamics and reduces strain.
- Cardiovascular Efficiency: A strong heart and lungs support endurance.
- Galloping Gait: The double-suspension gallop allows all four legs to be off the ground at once.
These traits are finely tuned by evolution and selective breeding for performance.
How Fast Is Fast?
To put their speed into perspective:
- Greyhound (45 mph) can outrun a racehorse in short bursts.
- Usain Bolt, the fastest human, has reached speeds of about 27.8 mph.
- Cheetah, the fastest land animal, can hit 70 mph.
So while no dog can match the cheetah, breeds like the Greyhound are stunningly fast in their own right.

Choosing the Right Speedy Companion
Speed shouldn’t be the only factor in choosing a dog. Consider your lifestyle, living space, and how much time you can dedicate to training and exercise. While these breeds are impressive runners, they also offer companionship, loyalty, and love.
