Congrats on your upcoming nuptials!!!!! We had my husband's childhood lab(he's passed now) in our wedding as the ring bearer. I would just say practice with her so she won't get distracted by cameras, music, etc. And if you have an outfit for her get her used to it. Rebel(my husband's dog) carried a little pillow on his back for close to a month to get used to carrying the rings. I hope you post pics I would l to see how it turns out
