For those with a Classical bent a thread on naming your dog, paraphrased from the writings of Xenophon
Personally, I plan on having a brace of whippets at some point called Ptolemy and Heracles, or Heracles and Artemis if one is a bitch.
However, now I've seen the tweet with Shackleton's sled dogs' names... I like the idea of him having a dog called Amundsen, but Bummer? I'm pleased to see he had a Hercules though - great minds think alike!
