Alternative Names for Ring Bearer & Dog Escort

Hi! Our wedding is super non traditional, but we do have a few traditional elements we need help with. We wanted to include my two teen brothers in the wedding in some way. We’re keeping bridal party small, and they don’t like public speaking (so no speeches/readings), but they’ve expressed interest in being the “ring bearer” and our dog escort (walking our pup down the aisle). We don’t want to give them the traditional titles (we’re calling our flower girl the “flower child”, which goes with the boho theme we have too).

Any ideas on more unique titles for the traditional job of a ring bearer and dog escort?
