I recently read FederalMom's reply to the "What pets does everyone have?" post. She mentions wanting to adopt a greyhound soon.

When I was young I spent a lot of time at a greyhound kennel, mainly just helping out and spending social time these beautiful dogs.

Retired greyhounds make absolutely wonderful pets. Many people have the misconception they require a lot more exercise than other breeds. Not so, in fact retired racing greyhounds are probably the biggest couch potatoes in the universe. They are extremely placid dogs, very affectionate and social and most are great with children. With training most of them are suitable to be placed in homes where there are cats, they require less grooming than other breeds and are very good for people with disabilities or allergies. Though I would recommend people with allergies do a "test drive" first. The only extra need they have is to be kept inside, they have a very thin, fine coat so they feel the cold. Also you need to check local by-laws as in some places even retired greyhounds are required to wear a muzzle. This seems cruel, but realistically, they are sight hounds so the breed is inclined to chase other animals, though I have not heard of this being a big problem. They also make very poor watchdogs, so if you require a guarding component, forget it, they are likely to give a warm welcome and lick an intruder to death, rather than scare anyone off.

So, if you can "look outside the box" when thinking of adding to your family a greyhound may be just the dog for you. There are many organisations worldwide that organise greyhound adoptions. Where I live, there is a group called Greyhound Angels (I think they are worldwide), if you can't adopt, you can sponsor a Greyhound Angel. The Greyhound Angels also socialise, family test and cat test, so each dog is assessed carefully prior to adoption, some are also obedience trained.

Even if you don't agree with the racing aspect, and I understand that many people do not. It is a breed worthy of consideration.
