Modern day Greyhounds placed by adoption organizations are generally retired, trained athletes. Greyhounds are generally bred by professionals who are looking for speed, endurance and even temperament. Most are bred on "farms" located throughout the country where the breeders pay close attention to the physical soundness and emotional disposition of the puppies. As a result, hereditary physical and temperament problems have been avoided in the breed.
For the first year of their lives Greyhound puppies live together with their litter mates and are handled frequently by the breeders and other staff associated with the breeding "farm," but they are not exposed to other breeds of dogs. Consequently, they are surprisingly socialized to people and strangers but not to other breeds of dog.
Former racing Greyhounds have been trained to chase lures, usually mechanical. They are NOT vicious predators as many believe, but chase things that move by nature. It is the Greyhound's nature to run. They are sprinters who can run up to 45 miles an hour for very short periods. Some of them love to run; others are simply not interested after they retire.
