My GSD’s name is Falco. I wanted to name him Elvis, but my bride of 38 years won the discussion.... “Yes Dear” always wins.
Now, when I have trouble naming something and all else fails, I name the creature after a duck I had when I was a kid, “Fred”.
I recently named one of my new Muscovy ducks “Fred” and another one “Elvis”.
Of course this won’t help in your case, because you will never eat your dog, but the farm critters I raise for the table are all given names of democrat politicians, so that I don’t feel bad when I butcher the little bastards. :>) Six of my 26 chickens are named named “Obama one”, “Obama two”, etc. I named one “Pelosi”, but a weasel recently ate her... an omen I hope.
Good luck. Oh, how about Skippy?
Or, if he’s small and peaceful looking, how about “Killer, if he’s intimidating, call him “Peaches”.
Had a sister-in-law that wouldn’t eat our wonderful home grown steaks because they had names. Ed was the best one of the bunch!!!
