We have two Luna's living in our condo building supporting this list. (Just disregard the dead "joke.")
Both girls have been barkers. Today was the first time that black Luna didn't bark at us. She and Spike had a friendly sniff-around the other day--I guess that was enough. Or maybe it was the Santa-inspired coat that she wore today.
White Luna came out a few minutes later, barking up a storm. I've been trying to cultivate her, to get her to trust me. I've made progress, but we still have a long way to go.
