They're kinda in the middle. I rarely bump into another dog named Mandy, but I have met a few. However it's by no means unique. I've never met another dog named Nova, Luka or Buck. I've only run across one Buck, one Nova, and two or three dogs named Luca on a couple forums. And actually, the Lucas are all male and of course are spelled differently. I generally like more unique names, probably because my name is so common that I rarely even respond to it when people say it unless if it sounds like someone I know
