Certain breeds have incredible running speeds over short bursts. Greyhounds can hit 45 mph, Border Collies 30 mph
Very Fast
Actual speed depends on the breed, age, health, and build of each individual dog. But some general breed trends exist for sprint speed.
Varies
Dogs built for racing (ex. Greyhounds) are sprinters at heart. They tire after short blazing-fast distances.
Distance Differs
Selective breeding has created athletic breeds primed for bursts of intense speed via traits like a deep chest, flexible spine
Why So Fast
A Greyhound named Gavin recorded an incredible speed of 45.5 mph over a short sprint.
Fastest Ever
Your home dogs can probably run around 15-20 mph at full gallop. Their top speeds usually go unleashed outdoors with room to sprint flat out.
Home Advantage
It's enjoyable seeing dogs run all-out while playing fetch or zooming around off leash in safe open areas.
