Gall Mirabella used to train her dogs to do tricks (特技) when she was a kid. Eventually, her hobby turned into a career. Today, Mirabella works as a dog trainer for Ringling Bros. and Barnum & Bailey circus (马戏团). Backstage before a recent show, she talked to Time ForKids about why she chose this career path, how she selects (挑选) the dogs she trains and what it’s like to work in the circus.
