One of the misconceptions about retired racers is that they are aggressive dogs because most people have only seen photos of Greyhounds racing, with muzzles covering their faces. The muzzles are used to help protect racing Greyhounds from injury and to determine the winners of close races. Outside of the racetrack, however, Greyhounds are usually quiet, gentle, docile, and compliant. If you're looking for a watchdog, choose another breed. They blend well into families with well-mannered children.
Most Greyhounds love the company of other dogs, and many live happily with cats as well.
Some Greyhounds adapt well to homes with very small animals. Greyhounds don't need much exercise. Another myth about Greyhounds is that, because they're bred to race, they need lots of room to run and constant exercise. At the track, they only race once or twice a week. In homes, however, they romp for short bursts and then turn back into couch potatoes.
