How Universal Studios chooses the Grinch’s dog Max

Every holiday season, one of the most beloved moments of Universal Orlando Resort’s Grinchmas Holiday Spectacular is the appearance of Max, the Grinch’s faithful dog and fan favorite. More than just a supporting character, Max plays a central role in bringing warmth and humor to the show, instantly capturing the audience’s attention whenever he steps on stage.

Universal Studios works closely with professional trainers and animal rescue organizations to find dogs suited to play Max. Each dog chosen for the role is a rescue, selected not only for their appearance but also for their calm temperament and friendly nature. The dogs must be comfortable around crowds, bright lights, and loud sounds, ensuring they can safely and happily perform in a live theatrical environment.

Once selected, the dogs undergo a careful rehearsal process. They spend several days training alongside the Grinch and the Whos of Whoville, learning stage cues and movements. This preparation allows them to confidently interact with performers and hit key moments in the show, including sitting beside the Grinch or participating in playful interactions that draw laughter from the audience.

Audience reactions to Max are often immediate and enthusiastic. The moment he appears, audible gasps and smiles ripple through the crowd, making him one of the most memorable elements of the holiday production. For many visitors, Max’s presence adds an extra layer of charm and emotional connection to the performance.

Care for the dogs extends beyond their time on stage. After completing their run as Max, the dogs are typically adopted by their trainers or cast members, ensuring they transition into loving forever homes. This commitment reflects Universal’s emphasis on animal welfare and responsible performance practices.

Max’s role in the show mirrors the heart of the Grinch’s story — representing loyalty, compassion, and the power of kindness. Through thoughtful casting and care, Universal Studios ensures that Max continues to embody the spirit of Grinchmas, spreading joy to audiences year after year.
