I'll have to side with
Celuien (no thanks to her hate-motivated campaign against poor Alf) and vote:
++ Moon Dog
The first reason being: I was going to vote that way anyway, so I'm not really siding with Cel anyways.
The second reason being: Well, we already evicted most of the other dogs on not much reasoning, might as well finish another off.
The third being there was only enough room for one "Moon" character in this challenge - The Man In-the-Moon - who's long since gone.
And lastly, "Moon" has such a negative connotation these days...
