QotD: Rover

Tomorrow, my bride is attending a Bible study with a bunch of women (though that doesn't bear on this tale). The topic: Abraham's bride, Sarah. Back then folks lived longer than we do today. In the earlier pages of Scripture, they lived a really long time. Amidst the conversation, my son mused,

"I'm pretty sure they lived in dog years back then."

Would that mean Moses carried around the Arf of the Covenant?
