I can empathise with trying out names that aren't too embarrassing to call out in public! Guide Dogs names each litter by consecutive letters of the alphabet. When you've got the second litter of the year with the letter U to name and there are seven pups some pretty weird named dogs arrived at training. Try calling,"Ursula!" to a black 100lb GSD in a crowded park. "Ulna" (!) was another one sure to get weird looks and "Yuko" and "Prudence" turned heads too.
