how fast can greyhounds run

Greyhounds can run at speeds up to approximately 45 miles per hour (72 kilometers per hour), making them the fastest dog breed in the world. The fastest recorded 100-meter sprint by a greyhound was 5.53 seconds, set by Brett Lee in 2001. Racing greyhounds usually win races at speeds between 36 to 38 mph (58–61 km/h), and they can reach top speeds of around 40–45 mph within just a few strides. Their unique physical features, such as a sleek aerodynamic body, powerful muscles, a flexible spine, and efficient cardiovascular system, contribute to their exceptional speed and acceleration capabilities.
