For the record, greyhounds are wonderful dogs. Their only drawback (if you call it that) is that they never bark. So if you're interested in a watchdog, forget it.

One thing to keep in mind is that when getting a dog/cat from the pound, tack on an extra $100 at least to cure it of the worms/ear mites/ticks/fleas/conjunctivitis/etc that it's BOUND to have caught from one of the other dozens of animals at the shelter. I once got a "free" cat from the pound that ended up costing me $175 on the first day I had him. Still, he was a wonderful cat.
