Thirteen U.S. House members want an audit of five agencies that have used dogs in experiments that caused them pain and distress. Here, Nevada Sen. Mark Manendo, D-Las Vegas, enters the Legislative Building in Carson City, Nev., on March 24, 2015, with rescue beagles Dean and Luke. Manendo introduced a bill that would require laboratories that conduct research on dogs and cats to put the animals up for adoption after the study work. Cathleen Allison AP
