Dog Breeds Ranked by Speed: From Slowest to Fastest

 How fast can different dog breeds actually run?
Some dogs barely reach 10 miles per hour. Others can go over 40. And in this video, we are ranking dog breeds from the slowest to the fastest, based on their estimated top speed.
But one quick disclaimer before we begin: dog speed is not an exact science. Some breeds have reliable racing or sport data behind them, while others are based more on breed estimates and owner reports. So don’t think of every number as a perfect world record. Think of it as a realistic comparison of what a healthy adult dog of that breed may be capable of.
And with that said… let’s start the race.
Most dogs are much faster than people realize. The average healthy pet dog can usually run somewhere between 15 and 20 miles per hour. That already means many dogs can outrun the average human without much effort.
That brings up an important question. Why are dogs so fast?
And a big part of it is their anatomy. When a dog runs, its spine bends and stretches like a spring. This helps the body extend forward, then compress again, allowing the dog to cover more ground with every stride. Dogs also have powerful rear legs, flexible shoulders, and no collarbones like humans do, which gives the front legs more freedom of movement. In fast breeds, all of this is combined with long legs, a deep chest, a light body, and a narrow, aerodynamic head.
But not every dog was bred for the same type of movement.
Some breeds were created to sprint after prey in open landscapes. Others were bred to herd sheep, pull sleds, guard livestock, track scent, or simply keep people company. That is why speed varies so much from breed to breed. A Pug and a Greyhound are both dogs, but they are built for completely different jobs.
Body shape matters a lot. Long-legged, lean breeds usually have the advantage in pure speed. Short-legged breeds like Dachshunds and Corgis can be surprisingly quick, but they simply cannot match the stride length of a sighthound. Flat-faced breeds like Bulldogs, French Bulldogs, and Pugs are slower not because they lack spirit, but because breathing and cooling down during intense exercise is much harder for them.
Size alone does not decide everything either. Some giant breeds are powerful, but not especially fast. And some small terriers can explode forward with shocking speed because they are light, muscular, and full of drive.
Age and fitness matter too. Most dogs reach their athletic peak as young adults, usually between two and five years old. Puppies should not be pushed into hard running because their joints are still developing, and senior dogs naturally slow down as their muscles and joints age. A fit, lean dog will almost always run better than an overweight dog of the same breed.
So as you can see a dog’s speed is more than just a fun number.
It tells a story about anatomy, history, instinct, breeding, and behavior.
From the slowest little companions to the fastest canine athletes on Earth, every breed in this ranking was built for something.
Some were built for comfort.
Some were built for endurance.
And some… were built for pure speed.
