Official Dog Walker

My granddaughter has been adamant that she hold Zoe's leash when we walk up to fetch the mail. She likes to run, and so does Zoe, so they are a pretty good team. Today was cold, so we bundled up for our walk. We have no problem with the coat, gloves, and boots, but the hat has been an issue. How do you put a hat over a topknot? Or a JoJo bow? Or a high ponytail? I am still working out the details. Any suggestions?
