As irresistible as a flying bulldog is, Mr. Bentley’s most famous move is ground-based, if not earth-bound. He moonwalks, and he’s good at it. Down hallways, across kitchen floors, out the glossy foyer of a high-class hotel, Mr. Bentley slides his back paws like Michael Jackson and backwards-scoots to his destination. If it’s funny to read about, it’s downright hysterical to watch, but it wasn’t until he’d been doing it for years that Mr. Bentley’s moonwalk went stratospheric. Because Mr. Bentley was Foy’s first dog, she didn’t realize that his reverse gear was anything unusual. “He just would do it based on his own weird dog logic,” she says. “I thought every dog did it.” Then she started dating Friesen, who immediately recognized Mr. Bentley’s dance moves as something special. Friesen suggested that Foy share the bulldog back-up with the world. “I was playing with him and throwing his toys, and he would pick it up and bring it back backwards,” says Friesen. “I thought she taught him to do it, but she said he just did it on his own. And then she said, ‘Why? Is that weird?’”
