It definitely isn’t politically correct but you could name your dog anything and there is nothing almost anyone could do. Of course if the name is to “crude” others might look under the covers to see if they can find any animal cruelty but if you’re above board the name will stick even if it offends the world. Unlike human’s dogs really don’t know and they don’t have the power to change their own name. I’m not recommending you act in such a fashion but if you do please chose a name that makes us all laugh not cry.
