What kind of dog does your wife want? Remember, she has to live with the dog when you're deployed and not around to help take care of it.
I didn't mean it the way it sounded. I'm new to the 'dog world' and I'm guilty of certain perceptions. I just picture a greyhound chasing a rabbit around a racetrack. I've been learning a lot lately looking at different breeds, and from what I've read greyhounds seem like a great companion dog. I just have never seen one in a home.
I guess if I take one running I don't have to worry about it keeping up! I'd probably bore it "Um, dude.. can you go any faster?"
