Tikka is sleeping at my feet as I type this... when I named her I thought it was unique, I have since heard of a cat named Tikka, see on a few posts up and saw a Tikka retrieving pheasants on Canada in the rough... now that was funny watching the show with my dog in the room, every time they said "Tikka" and whistled, my dog would perk up and look at the TV.
I have always struggled with female name for dogs, male are not so bad, my father named his beagles Butcher (butch) and Chaser, His father had one named Roamer. These are all perfect names for beagles. So maybe if you want something unique, get your head away from guns per say and think about what this dog will be doing in the field.
