I didn't name my current two, but they are 'Villain' and 'Flirtt'. I'm sure noone out there needs an explanation on meaning, lol. Villain is 'Flamin' Villain'. Both dogs named by breeders. I call them 'the crook and the hussey', or 'Bogey and Bacall', occasionally 'Humph and Loz' ( for those old enough, lol ). Villain generally gets 'Villi' when not working, and Flirtt gets 'Floozy'.
I prefer dog names that aren't human ones. Previously our family have had Kealan, Kiera, Francie, Imala ( dark one ) and Morgaine the Irish Wolfhounds ( I didn't name them either ), Kurgon the Dobe ( from the old movie 'The Highlander' ), Ruffael and Khorann the Afghan hounds, and Memphis and Texas the Kelpie X's ( I named those four ).
