It is a soft and intelligent breed that often becomes attached to its owners. It is the fastest breed of dog on the planet. A combination of long, powerful legs, deep chest and aerodynamic build allows it to reach speeds of up to 72 km/h (45 mph) in less than one and a half seconds, or within 3 strides.
