Greyhounds are defined as the fastest dog breed in the world, a tall, muscular, smooth-coated. Greyhounds are a separate breed from other related sighthounds, such as the Italian greyhound.
The Greyhound is a gentle and intelligent breed whose combination of long, powerful legs, deep chest, flexible spine, and slim build allows it to reach average race speeds exceeding 64 kilometres per hour (40 mph). The Greyhound can reach a full speed of at least 21.3 m/s (77 km/h) (47 Mph) as recorded by Shall Not on the Richmond straight track on April 29, 2023 for the second sectional between 110m and 220m.
