To celebrate its 1-year anniversary, The Dog Haus in Pasadena is giving away free hot dogs tomorrow, October 20th. The gourmet hot dog shop is doing so well, owners Hagop Giragossian, Quasim Riaz, André Vener and Robert and Denise Zeilstra plan to open two more locations by the end of this year, one in the heart of Old Pasadena and the other in Alhambra.
