A name for a new puppy?

We're getting a miniature Daschund/ Chihuahua mix puppy from a rescue shelter. His name is Matty, but it sounds more like a girl name. We were thinking of Rudy (Rudi) or Levi. Do you guys have any ideas for a different name? Please&&Thankyouu! :) Btw, our other two dogs are named Ripley and Fritz.
