Danny's Doodles: The Dog Biscuit Breakfast

Danny knows his friend Calvin has crazy ideas, so he's not surprised when Calvin suggests they start a Rent-a-Pet business. After all, Calvin's Aunt Ruth wants the boys to watch her dog while she's away, and what better way to get the miniature Collie off their hands than loaning him to a kid in the neighborhood for a few days?

But in order to rent a pet, you need a renter. Which Calvin and Danny don't have. Can the two drum up some business before it's too late? Or will their plan go to the dogs?
