I'm a HUGE greyhound fan. Some don't do so well being left alone for hours though, but there are SO many to choose from that you should be able to find one that is fine to be left alone. Greyhounds can be difficult to train, but they are just as affectionate as labs.
It also depends on how much exercise you're able to provide the dog. For the most part, labs need more exercise than greyhounds. But just because greys are usually "couch potatoes" doesn't mean they don't need daily structured exercise.
