10 Smokin' Secrets About Max: The Untold Story Of 'The Dog In The Mask' (Milo)

The dog in the mask is a cinematic icon whose legacy endures decades after his debut. As of December 17, 2025, the character of Milo, Jim Carrey's loyal Jack Russell Terrier in the 1994 blockbuster *The Mask*, remains one of the most beloved and talented animal actors in Hollywood history. This article dives deep into the untold story of Max, the dog actor who brought Milo to life, revealing the intense training, on-set improvisations, and lasting cultural impact of the canine star who famously stole the magical Norse artifact. Max, the five-year-old Jack Russell Terrier, was an absolute scene-stealer, matching the frenetic energy of his human co-star, Jim Carrey (Stanley Ipkiss), and delivering a performance that was far more than just a simple trick. The production team considered Max to be the cast member with the most film experience, a testament to his professionalism and the extraordinary skills of his trainer. His pivotal role in the film—donning the powerful Mask of Loki and becoming a green, cartoonish whirlwind—cemented his place in movie history, making "the dog in the mask" a phrase synonymous with 90s cinema magic.

The Complete Profile of Max, the Dog Actor

While the character is known worldwide as Milo, the real star behind the green-faced canine was a highly trained Jack Russell Terrier named Max. His performance alongside Jim Carrey is widely regarded as one of the best by an animal actor, showcasing remarkable obedience, timing, and even apparent improvisation.

• Age During Filming: Approximately 5 years old
• Owner/Co-Star: Stanley Ipkiss (played by Jim Carrey)
• Film Debut: The Mask (1994)

• Key Scene: Donning the Mask of Loki to become a miniature green, cigar-smoking, gun-toting cartoon villain to save Stanley from the police and the villain Tyrell (Peter Greene).

Max’s trainer, Mark Forbes, is a renowned animal coordinator in Hollywood. Forbes’s approach was instrumental in Max’s success, ensuring the dog was not just performing tricks but acting within the scene's context. The bond between Max and Carrey was also key; the two reportedly spent a lot of time together off-camera, which translated into their incredible on-screen chemistry. The natural rapport between the man and his dog made the relationship between Stanley and Milo feel genuine, adding emotional depth to the otherwise cartoonish comedy.

The Untold Secrets Behind the Iconic 'Masked Dog' Scene

The moment Milo catches the Mask of Loki mid-air and subsequently transforms into a miniature, green-faced menace is the film's most memorable dog-centric sequence. This scene was not only a comedic highlight but a crucial plot device, and its execution required masterful animal training and cinematic trickery. Many fans wonder how such a complex action, where a dog seems to willingly put on a heavy, oversized prop, was achieved.

1. The Training Program Was Rigorous and Positive

Trainer Mark Forbes used a positive reinforcement method to prepare Max for the role. The Jack Russell Terrier breed is known for its high energy and intelligence, making them excellent candidates for complex training, but their stubbornness can be a challenge. Max was trained to hold objects in his mouth and to associate the heavy, rubber Mask prop with a reward. The secret was not forcing the dog to wear it, but making him want to interact with it.

The prop department created a specific, lightweight rubber version of the Mask for Max to carry and wear. Crucially, the mask Max wore in the close-up shots was not the full, heavy wooden or plastic prop. This special version was designed to sit comfortably on the dog's head, and Max was trained to hold his head still for the duration of the shot, which required immense focus and discipline. The transformation sequence itself relied heavily on early CGI and practical effects, but the live-action shots of Max in the Mask are genuine.

3. Max's Improvised Moment with Jim Carrey

Max's talent extended beyond his training. During one scene, where Stanley Ipkiss is trying to teach Milo to play fetch with a frisbee, the dog was supposed to simply bring the frisbee back. However, Max, showing his spirited Jack Russell nature, unexpectedly bit the frisbee instead of dropping it. Jim Carrey, a master of improvisation, immediately reacted to this unscripted moment, which was kept in the final cut. This ability to "match wits" with Carrey made Max a true co-star and not just a prop.

4. The "Milo Saves the Day" Plot Twist

In the film, Milo's action is pivotal. After Stanley is arrested, Milo retrieves the Mask, brings it to his owner in the police station, and then, in the final showdown, puts it on himself. The decision to have the dog don the Mask was a departure from the original, darker tone of the Dark Horse Comics series, which focused more on horror elements. The film adaptation, directed by Chuck Russell, embraced a more cartoonish, zany energy, and Milo's transformation perfectly encapsulated this shift, adding a layer of wholesome, albeit chaotic, heroism to the climax.

Max’s Enduring Legacy and the Future of the Canine Mask

Max the Jack Russell Terrier may have only starred in a handful of films, but his role as Milo in *The Mask* ensured his immortality in pop culture. His performance had a significant, lasting impact on both the film industry and the popularity of his breed.

The Jack Russell Terrier Popularity Spike

Following the massive box office success of *The Mask* (grossing over $350 million worldwide), the Jack Russell Terrier experienced a surge in popularity. The breed, already known for its energetic and fearless nature, was suddenly viewed as the ideal family dog—intelligent, loyal, and capable of great feats, much like Milo. This phenomenon is a common occurrence in Hollywood, where a popular animal actor can single-handedly influence pet ownership trends for years to follow.

The 'Smokin' Dog' Meme and Cultural Entity

Milo’s green-faced, cigar-smoking persona has become a timeless meme and a shorthand for unexpected, chaotic energy. The image of the dog in the mask is instantly recognizable and is often cited in lists of the greatest movie dogs of all time. His ability to perform complex stunts, from running on two legs to fighting the bad guys, solidified his status as a cinematic legend, often earning him the title of "the real star" of the film.

The Mask Sequel and Reboot Rumors

For years, there have been talks about a sequel or a reboot to *The Mask*. While the 2005 sequel, *Son of the Mask*, did not feature Milo, the character is often brought up in discussions about a potential new entry. Fans and critics often suggest that any successful reboot would need to recapture the magic of the original, and that includes the chaotic, loyal presence of Stanley Ipkiss's dog. The enduring popularity of Milo proves that the concept of the Mask falling into the paws of a lovable pet is a comedic goldmine that future filmmakers will likely try to tap into again.

The story of Max, the dog in the mask, is a perfect illustration of how a talented animal, coupled with an expert trainer and a great script, can create a character that transcends the film itself. Max’s legacy lives on through the countless fans who still quote Stanley Ipkiss's famous line, "Milo, you're the best dog in the world," a sentiment that remains true for the Jack Russell Terrier who truly was "smokin’" on the silver screen.
