Max was the cutest character in the 2000 How the Grinch Stole Christmas(and, TBH, every adaption of The Grinch), but did you know he was actually played by six different mixed-breed shelter rescue dogs? Humane Hollywood says he was played by Kelly, Chip, Topsy, Stella, Zelda, and Bo, who all wore a lightweight headpiece with long ears attached and an additional antler headpiece and fur-covered harness on the flying scenes.
