The father and son duo are currently shooting the second season of their History Channel docuseries, Ozzy & Jack's World Detour, where they go on adventures to different landmarks across the globe to learn more about the history and culture of those locales.
Over the past few days, Jack's been sharing snapshots of their adventure along Route 66, including a cute pic of Pearl in front of a 1860s-era Arizona jail.
"She's escaped!! Pearls been traveling me and Papa this week. It's been a total blast. I love having her come to work with us," Jack wrote.
