Fastest Dog Breeds by Top Speed
The Greyhound is the second-fastest land animal on earth over a sprint. Here's how the quickest breeds stack up — and why you should treat the exact numbers with caution.
How we built it
Ordered by commonly cited top running speed, compiled from sighthound racing data and breed-club estimates. We link each breed to its full PetGrit profile.
Some dogs are built to run. Sighthounds like the Greyhound and Afghan Hound were bred over millennia to chase down fast game by sight, and they reach speeds that put most athletes to shame. Below is a ranking of fast breeds by estimated top speed. One honest caveat up front: apart from the Greyhound — whose ~45 mph sprint is well documented — most of these figures are widely repeated estimates rather than precisely measured numbers, and any individual dog varies a lot.

- 1 ≈45 mph
Greyhound
Hound Group · Large
The undisputed fastest dog breed — a purpose-built sprinter that accelerates to near-cheetah speeds over a few hundred metres, then happily naps all day.

≈40 mphAfghan Hound
Hound Group · Large
An ancient sighthound bred to course game across rough terrain; glamorous coat, serious engine underneath.

Sporting group · Medium-Large
A lean, tireless Hungarian gundog with the stamina to run hard for hours, not just sprint.
View profile - 4

Terrier · Small
Astonishingly fast for its size — a compact bundle of muscle and drive that can outrun dogs three times its weight.
View profile - 5
≈37 mphDalmatian
Non-sporting group · Large
Bred to trot beside carriages for miles, the Dalmatian pairs real speed with exceptional endurance.
View profile - 6
≈35 mphWhippet

≈32 mphDoberman Pinscher
Working group · Large
Fast and agile as well as smart — a working breed that covers ground quickly.
View profile - 9
≈30 mphBorder Collie
Herding group · Medium
Quick and endlessly nimble; the speed serves the herding brain, changing direction on a dime.
View profile - 10
≈30 mphGerman Shepherd
Herding group · Large
A capable sprinter for a big working dog, which is part of why it excels in police and protection roles.

Sources & method
- Greyhound racing performance data — The basis for the well-established ~45 mph Greyhound top speed.
- Breed-club and sighthound coursing estimates — Approximate top speeds for the remaining breeds; figures vary by source.
The short version
- The Greyhound is the fastest dog breed at roughly 45 mph — the second-fastest land animal over a short sprint, behind only the cheetah.
- Sighthounds (Greyhound, Afghan Hound, Whippet) dominate the top of the list because they were bred specifically to chase fast game by sight.
- Most speed figures below the Greyhound are estimates that vary by source — and many of the fastest breeds are sprinters that are calm couch dogs the rest of the day.
Frequently asked questions
What is the fastest dog breed?
The Greyhound, at a top speed of roughly 45 mph (72 km/h). It's the fastest dog breed by a clear margin and the second-fastest land animal on earth over a short distance, behind only the cheetah. Greyhounds are sprinters, though — they're famously lazy and content to lounge for most of the day.
How accurate are these dog speed numbers?
Only loosely, apart from the Greyhound. The Greyhound's ~45 mph is well documented from racing. The other figures are widely repeated estimates that differ between sources and don't account for an individual dog's build, fitness, or age, so treat the exact mph as a ballpark rather than a measured fact.
Are fast dogs high-energy dogs?
Not always. Sprinting breeds like the Greyhound and Whippet are surprisingly low-energy at home — they need a daily sprint and then sleep most of the day. Endurance breeds like the Vizsla, Weimaraner, and Dalmatian are the genuinely high-stamina ones that need hours of activity to be content.
