For the second straight summer, Walter Station Brewery in east Phoenix is collaborating with the Arizona Animal Welfare League, Arizona’s largest and oldest no-kill shelter, to raise money for AAWL’s life-saving pet programs. The brewery is making a special beer, Ale Wagger, available for a limited time on tap and in six-packs of cans. A portion of the proceeds go to the AAWL. An official launch party will be held 11 a.m. to 2 p.m. Saturday, Aug. 20, at the brewery.
