You know the sound. It’s a wheezy, raspy, rhythmic series of huffs that sounds like an old radiator trying to clear its throat. It’s cynical. It’s petty. It’s absolutely iconic. When we talk about the Muttley laugh, we aren’t just talking about a cartoon sound effect; we’re talking about a masterclass in character design that redefined how we perceive sidekicks in animation.
Don Messick, the legendary voice actor, didn't just stumble into that sound. He crafted it. If you grew up watching Wacky Races or Dastardly and Muttley in Their Flying Machines, that snickering dog was probably your favorite part of the show, even if he was technically one of the "bad guys." He was the king of the "I told you so" without ever saying a single word.
The Secret Sauce Behind the Snicker
Most people think Muttley was just a mean-spirited dog. Not really. He was an employee who was perpetually over it. His laugh was his only rebellion against the incompetence of his boss, Dick Dastardly.
The Muttley laugh is technically known as a "wheezy snicker." Messick used a technique where he would inhale and exhale sharply while tightening his vocal cords, creating that signature staccato rhythm. It’s a sound that communicates pure schadenfreude—the joy of watching someone else fail. When Dastardly’s complex schemes inevitably blew up in his face, Muttley wasn't there to help. He was there to laugh at the debris.
Think about the timing. The laugh never came during the planning phase. It waited. It lingered until the exact moment of peak failure. This wasn't just random noise; it was comedic punctuation.
Hanna-Barbera knew they had gold. They actually used variations of this wheeze for other characters, like Precious Pupp and even Mumbly, who looks suspiciously like Muttley but wears a trench coat and works as a detective. But Muttley is the one who owns it. He’s the original. Honestly, the way he covers his mouth with his paw while doing it just adds that extra layer of "I'm trying to be polite but you're actually an idiot."

Why the Animation World Changed Because of a Wheeze
Before the late 1960s, sidekicks were often just there to agree with the lead. They were the "Yes men." Muttley flipped the script. He was the first high-profile cynical sidekick who actively rooted for his partner's downfall.
This shift in character dynamics allowed writers to explore more complex humor. You weren't just laughing at the slapstick; you were laughing at the relationship between the two characters. The Muttley laugh became a shorthand for "I knew this would happen." It’s a universal feeling. We've all had that coworker or friend who ignores our advice, fails spectacularly, and all we want to do is wheeze in the corner.
The Technical Evolution of the Sound
If you listen closely to the early episodes of Wacky Races (1968), the laugh is a bit more guttural. As the character moved into Dastardly and Muttley in Their Flying Machines (1969), Messick refined it. He made it more "airy."
- It’s a three-part sound: the initial "huff," the rhythmic middle, and the trailing whistle.
- The animation had to match. The shoulders have to bounce. If the shoulders don't bounce, the laugh doesn't feel real.
- The frequency of the laugh was used to fill "dead air" in limited animation, a common tactic for Hanna-Barbera to save money while keeping the energy high.
It’s actually pretty difficult to mimic perfectly. Most people try to do it by just coughing, but you have to get that specific whistle in the throat. Messick was a genius of breath control. He also voiced Scooby-Doo and Papa Smurf, but Muttley required a level of physical exertion that most of his other roles didn't.
The Controversy: Muttley vs. Mumbly
There is a weird amount of confusion online about whether Muttley and Mumbly are the same dog. They aren't. They’re cousins, maybe, in the way all cartoon assets were recycled back then.

Mumbly appeared later, in 1976. He had the same laugh, the same wheeze, and the same voice actor. But while Muttley was a pilot/racer/henchman, Mumbly was a detective. Fans get heated about this. If you call Mumbly "Muttley," you're going to get corrected by a purist. The difference is subtle but real. Muttley’s laugh is sharper. It’s meaner. Mumbly’s snicker is a bit more self-satisfied, almost like he’s solved the crime before you have.
The Cultural Legacy of the Snicker
Why does a dog from 1968 still trend on social media? Because the Muttley laugh is the ultimate reaction meme.
In the era of TikTok and Reels, that audio clip is a goldmine. It’s used to highlight "fails" across every niche imaginable. It’s a sound that transcends language barriers. You don’t need to speak English to understand that a wheezing dog is making fun of you. It’s a primal sound of mockery.
There’s also the "Muttley Syndrome." This is a term sometimes used by animators to describe a character who steals the spotlight without having any dialogue. He doesn't need a monologue. He doesn't need a backstory. He just needs a specific, recognizable reaction.
What You Probably Didn't Know
Muttley actually had a few words. He’d grumble "Razzle frazzle" or "Sassafras" when he was really annoyed. But the laugh was his primary mode of communication. It served as a bridge between the animal world and the human world. He was smarter than Dastardly, and he knew it. That’s the power of the character. He wasn't a pet; he was a silent partner with a very loud opinion.

The laugh also served as a precursor to characters like Rocket Raccoon. The "grumpy, smarter-than-the-hero, cynical animal" trope owes a massive debt to a brown dog in a flying machine.
How to Spot a "Muttley" in Real Life
We all know one. It’s the person who sits in the back of the meeting, says nothing while a terrible idea is being pitched, and then lets out a tiny, barely audible snicker when the project fails three months later.
The Muttley laugh is the soundtrack of the cynical realist. It’s not about being a villain; it’s about being right in the most annoying way possible.
Actionable Insights for Fans and Creators
If you're looking to dive deeper into the world of classic animation or even use these techniques in your own content, here’s what you should actually do:
- Study Don Messick’s Range: Don’t just listen to Muttley. Contrast it with his work as Astro from The Jetsons. Understanding how a single actor can use breath and "vocal fry" to create distinct personalities is a masterclass in voice acting.
- Analyze the "Beat": In comedy, the "Muttley beat" is the pause after a failure but before the reaction. If you’re editing video, wait 0.5 seconds longer than you think you should before dropping in a reaction sound. That’s where the humor lives.
- Check the Credits: Look for Iwao Takamoto’s character designs. He’s the one who gave Muttley those expressive eyes and the "paw-over-mouth" gesture that made the laugh work visually.
- Identify the Archetype: Next time you’re watching a modern sitcom, look for the "Muttley." They are the character who exists solely to react to the protagonist’s ego. Seeing how this role has evolved from 1968 to today explains a lot about modern comedy structures.
The Muttley laugh isn't just nostalgia. It’s a blueprint for how to build a character out of thin air—or in this case, a very thin, wheezy breath. It’s proof that sometimes, saying nothing and just laughing at the chaos is the most effective way to be heard.
