I currently have a retired racer. He is the third greyhound I have adopted over the years. I mostly had two of them at a time but I now have a rescued Malamute with my grey, my female grey died a few years back. I have several cats too. Generally they are very docile and sweet. Not high strung or overly active. A few have a very high prey drive and can not be homed with small dogs or cats etc. The majority is fine with them. I used to foster greys and also temperament tested them as to their compability with cats....I'd say about 90% of them were good with cats from the beginning or adjusted farly quickly. The rest was not suitable to live with smaller pets due to high prey drive or other issues. The industry is not supposed to use live rabbits or kittens for training anymore but some of the trainers may not follow the rules. I do not leave my dogs out with the chickens, the grey usully does not care about them, ignores them (interested in the feed though) but once in a while he gets the bug to run in the group of chickens and watch them scaatter..I swear he laughs. He does not pick them up or run after them but it is scary for the chickens and don't want to risk that he grabs a chicken. So we have either a barrier up or the chickens are already in the coop when he races n the yard.Anyway, greyhounds should never be allowed off leash unless fenced in. When they take off after something you may not be able to get them back. So they are 40 mile per hour couch potatoes.....mostly lounging around with a few minutes a couple of times a day outbursts of energy. They need less exercise than many other breeds, have to be 'build up' for longer walks as they are bred to sprint short distances and are mostly confined in cages on the track. Most health problems are old injuries (fractures, tendon, joint problems and their teeth are often not in good shape. Anyway, most greys do well in a home with walks and occasional playtime/run in a fenced yard or dog park. They are however not suited for extreme temperatures and should be pretty much house dogs. They overheat easily in summer heat and have little hair and bodyfat to insulate when it's cold. Cynthia Branigan wrote acouple of very good books about keeping ex racers. She is a wonderful lady, I only had the pleasure to meet her once but I would read her books. If you have any questions, please PM or e-mail me...... Greyhound people can go on and on - just like chicken people.
