All my dogs are second-hand, other people's castoffs, so I didn't get to name them myself. Unless you count changing Rocky to Roxy (since she's a girl) as naming.
We finally named her Sophie, because it's actually my mom's dog, so she got to do the final picking. Now when we do her pedigree papers, we need another three-word name. I'm pulling for Mordenkainen's Faithful Hound.
