Sorry things didn't work out with Peabo, but it's understandable that she would want to keep him close. Maybe Dillon is a better alternative anyways? The good thing is there is a lot of word of mouth between breeders, so they may hear of someone who has an adult to place that might work out for you. Don't be afraid to contact other breeders that are closer to you too, even if there's nothing on their site, they may know of something available or would keep you in mind if something comes up later.
Andrea is right, Piggy may or may not be a truly dominant girl, but either way, you want a laid back submissive boy to pair with her. Two crazy dogs will definitely make your life crazy! lol A puppy is usually the best bet for introducing to an established dog, especially a dominant one. However the good thing with adding an adult is that you'll usually see their real side right away. A puppy may change behavior as they grow up and get away from their littermates and what starts out as a nice pairing might not work out later. But again, usually the puppy will work out better than an adult on average.
Regarding the Sundance guy, if it's who I think it is, then yes you want to steer clear. I don't know him but have heard about him from a few folks and I did run into some of the vet techs that see his dogs, at a booth for a pet expo. And when they saw my dogs they couldn't believe that the breed was actually nice! I had all 4 of mine on leash together and they walked up and gave kisses to the girls. Apparently his dogs have to come in the door muzzled. Also for health testing, if you don't see his dogs on OFA, that's probably another big clue.
