Last October, fast-casual chain Dog Haus signed a $500 million franchise deal with American Development Partners to open more than 300 units in 12 states over the next seven years. The deal includes an unnamed private-equity firm that will provide capital for real estate and construction, and the units will be operated by veteran franchisees. Dog Haus currently has stores in Arizona, California, Colorado, Nevada and Utah offering hot dogs, sausages, burgers and sliders. Some stores are tagged as Biergarten, with expanded craft beer offerings.
