Love this site…As a breeder of Corgis I am always trying to come up with unique names for my puppies. I like to name the litter after the first letter of the mommas name so it does get pretty challenging after a while especially if I have females that both have the same first letter. I 💕 the list you have come up with. Very good collection of unique names. Thanks…I can’t wait for a litter that starts with “O”…Outlaw is going to be the first one I use.
