Racers are raised and live in the company of other Greyhounds. They are not aggressive an usually accept most other dogs. But they are hunters by nature and it would be asking a lot of a greyhound to distinguish between cats and the small furry animals they are bred to hunt. This knowledge can readily be transferred to their new home, but you must teach them where it is acceptable for them to relieve themselves. Yes, and most greyhounds have already been broken to the lead.
Greyhounds prefer to walk on a slack lead and, for dogs of their size, are unusually easy to handle.
They respond well to touch and voice commands as well. About as much as any other large dog. Older greyhounds are more sedentary, but they enjoy walking and often make superb jogging companions. First of all, racing greyhounds spend a good portion of their lives in their own kennel crate. It is something they are used to, and during the unfamiliar process of being adopted, the familiarity of the crate will be a welcome sight.
