Who would want a pet cat or dog when you could have a pet pig? Jack certainly wouldn’t accept anything less. Zach is Jack’s best friend, he just happens to be a 60 lb. pot belly pig. Although sometimes lazy and uncooperative, Zach and Jack are inseparable. Jack and Zach are able to communicate with one another through a series of snorts, squeals, and oinks. It’s a shame that pigs aren’t allowed inside any fine dining establishments unless they are a part of the menu.
