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 selected the dogs she trains and what it’s like to work in the circus.
