In 2000's live-action version of How The Grinch Stole Christmas, Jim Carrey's 'Grinch' has a loyal dog called 'Max' who helps him with his pesky schemes.
Animatronic dog Max featured in The Grinch
Although The Grinch's faithful hound was voiced by Frank Welker, he was apparently played by six different mixed-breed rescue shelter dogs as well as an animatronic version.
Jim Boulden was Animatronics and Puppet Creator for The Grinch, so I believe he is responsible for bringing this Max puppet to life on screen.
