Keep or change his name?

Hi all! I am hopefully adopting this very good boy today! 🤞🏼🤞🏼 His name currently is Rocco. He has been at the shelter for a couple weeks, came in as a stray. So that has only been his name for a couple weeks, but he definitely already knows it. If I kept it, I think I would spell it Rocko like Rocko’s Modern Life. But I’m also thinking about other good names for him. I am pretty sure he is a Chihuahua/ Jack Russel mix. I kinda like Cheddar, or Colby Jack lol. But I would love to hear any ideas you might have!
