DENVER, CO - MAY 17: Bartender Erika DeLine fills a Weiss glass with Weissbier at Prost  Brewing at 2540 19th Street on May 17, 2016 in Denver, Colorado.  Denver's health department has been pushing back against tap rooms that are dog friendly.  They say even thought the tap rooms don't sell food, beer counts as food.  Breweries are planning on fighting back in hopes to continue to allow people and their canine companions to enjoy going to breweries together.  (Photo by Helen H.
