Shake Shack is pet-friendly and one of the optional names the founder made for this restaurant was actually Dog Run. A lover of dogs, the founder made sure pets get to eat great food at the restaurant, too. They offer the Pooch-ini in their menu, which are dog biscuits with peanut butter sauce and vanilla custard. A prepackaged treat is also sold at the restaurant, which is the Bag O' Bones. It contains 5 ShackBurger dog biscuits made by New York City's Bocce's Bakery.
