Welcome to Pet Talk! Well, you're in Texas, so whatever the breed it needs to be an indoor-mostly dog! Whew, it's gettin' gross already. What part of Texas are you in? If you're close to Dallas I'd be more than happy to assist you in your search and help you locate/meet shelter or rescue dogs. (I know of several rescues in the area and volunteer for a couple of them.)
I personally don't recommend either of my two small breeds (Toy Fox & Jack Russell), way to active and the JRT is hard to train. I personally don't think it's fair to have Huskies here, too hot, and Basenjis can very difficult to train for a first time owner.

A greyhound may very well be a good choice for you. Or even a Great Dane (major couch potatoes)

Some other questions to ask yourself:

Do you want a very active dog to run, hike, or bike with? (if yes, you'll HAVE to exercise this dog a LOT, EVERY day)

Do you want a couch potato that will occasionally want to go on a walk, hike, or play with toys?

Are you totally against a different size, even if everything else about the breed is perfect? (like activity level, trainability)

How much time are you willing to spend training?

Let me know if I can help, I'd be more than happy to.
