I adopted my Elvis (greyhound) when he was 3 1/2, and myself and DBF both work an 8 hour day. I know I could not handle a puppy right now, but an adult dog I believe can cope better. I did research for 2 years before deciding on a grey (narrowed it to a greyhound and a Great Dane). As above poster mentioned, Breed Rescue is a great way to go, because most will evaluate your lifestyle to see if that particular breed is well suited.

Good luck!
