I usually adopt. Call them by the name they were given (unless it’s really stupid then I’ll try to think of one) wait a few weeks, a nickname usually presents itself aaaaand that’s the new name. They’re not always winners but, when the damn dog only response to “Ass Clown” you’re kinda locked in =\
Yeah that’s actually how I ended up on Reddit back in the day. All the damn buzz feed articles. I just decided to cut out the middle man.
