Greyhound

The greyhound is a dog in the sighthound family.

Images from ancient Egypt suggest the greyhound or a close relative was domesticated very early in civilization.

Greyhounds are one of the fastest running of all dogs, with their long legs and lanky frames. They are commonly known for their use on the racetrack, where they can reach speeds up to 45 mph (72 km/h). The conditions under which hracing greyhounds are kept are considered by many people to be inhumane. In the late 20th century many greyhound adoption groups began taking greyhounds from the racetracks when they could not compete and placing them in adoptive homes. Before this, most retired greyhounds were killed. Many still are.

Some Greyhounds never race either because they are too slow, have physical defects or do not have the required temperament. Most finish racing between two and three years of age.

Although Greyhounds are extremely fast dogs, they are not high enery dogs. They are sprinters and do not require much excercise once they leave the track. They are quiet, gentle animals.

They make good pets because of their mild and affectionate character. They can get along well with children and family pets, including cats. They do not have undercoats and are considered "hypoallergenic."
