Greyhounds can reach speeds of up to 72 kilometres per hour (45 miles per hour) over short distances. They run so fast due to their unique combination of physical attributes, including long legs, flexible ‘hinged’ spine, deep chest, fast-twitch muscle fibres, highly efficient cardiovascular system, efficient breathing, high percentage of muscle, low body fat, and genetic selection. They are sometimes regarded as the Usain Bolts of the canine world due to their effortless sprinting at high speeds.
