Greyhounds are very sweet, gentle, affectionate, quiet, intelligent dogs.
They are not hyper and aggressive as many people believe. They can easily sleep 20 hours a day if left undisturbed. They are indoor dogs, not able to tolerate extreme temperatures because of their lack of body fat and thick fur. They typically get along well with children and other pets. The hounds are usually between the ages of 2 and 5, and can live to be 12 to 15 years old if all goes well.
