Hough has been spending downtime on the movie set of Rock of Ages with her Cavalier King Charles spaniels, and the littlest one, Harley, has charms even Cruise can’t resist.
“Tom was telling me about [daughter] Suri,” Hough says, “and that she would probably love Harley.”
Hough brought Harley home in April as a companion for pooch Lexi. For the actress/singer/dancer, having her beloved pups close while she’s at work in Miami is a must.
“They go everywhere with me,” she tells PEOPLE from the launch of the voting campaign for the Hero Dog Awards, which will air on the Hallmark Channel in November. “They are on set all the time, we take long walks. Adam Shankman, the director, has his two dogs there, too, so we’ve had a groomer come on set. It’s pretty funny.”
