Hmm, that's an interesting point. I'd heard that one or two syllable names are easier for dogs. Then again, I'd never really considered how close Scout sounds to Out, since I've always said "Outside" with my dogs.
Something I'll think about, he still hasn't gotten used to his name though, so I could resort to the second place name I had in mind...Ranger. Since the wife isn't always as consistent with commands, and rarely adds a hand signal like I do, it's a possibility she might just say "Out". Glad you brought that to my attention.
