* Top speed: Greyhounds can reach speeds of up to 45 mph (72 km/h) in short bursts.
* Sprint distance: They are built for short sprints, not long distances.
* Acceleration: Greyhounds can accelerate from 0 to 30 mph in just 3 seconds.
* Comparison: A greyhound's speed is comparable to a racehorse!
It's important to note that these are just estimates. Individual greyhounds can vary in speed and athleticism.
