Hmm... Saphire, or Saphi for short. Though it is a bit of a girl dog's name (Girlfriends Pet Labrador is called Saphire).
You are naming a DOG after me??? A dog?! I don't think I like that idea... I was going to suggest "Fluffy" but now I think you should name it "Anions"!
I once knew a bloke who called his dog Spliff One day it got out for a week or so and he put up posters saying 'Lost dog - goes by the name of Spliff - please return if found'
