I appreciate all of your responses guys, and I think that our minds are made up...we're getting a lab. Seems like the best option for a "jack-of-all-trades."
Bobby Urban -
We're definitely on the same page. We didn't even consider buying a dog, we always had the intent to adopt a dog from the shelter, preferably one that is at least 6 months old, but not more than two years old. We've been scanning petfinder to find possible dogs in our area for the last few weeks now. Definitely a lot of choices, and I'd feel much better about bringing one of those dogs home with me.
Also, I might try that antler-ball idea. That sounds like a easy but effective training technique.
Anyway, thanks for all your input, it's much appreciated.
