When we first introduced Mac as the Nandina Dog, he just seemed to be a natural fit with his black and white coat and expressive face. Little did we realize that in a community that takes their pets seriously, Mac would become so popular. Plus there isn't a creature alive that enjoys a good sofa or chair for a nap, quite like Mac does. In the future look for occasional product recommendations that receive a high Mac Factor; that elusive yet quantifiable score that rates the combination of comfort, style, and durability.
