My dog is Loki, after the viking trickster God of mischief, but when I originally got left with her (Poor, neglected thing that she was) she was called 'Snowy', me and the kids decided to change it because she'd obviously had a terrible time (her spine and ribs were showing) and wanted to give her a new start, we threw a load of names at her and she 'chose' Loki! On a brighter note- I had a rottweiler which I named 'Morpheus' after the Greek God of dreams. Loads of guys commented on it when I'd walk him and said it was a perfect name, I was impressed that eveyone knew their Greek mythology. And then I realised- the guys thought I was saying "More-fierce"!
