Snoopy may look like just a plain black-and-white beagle, but this little war veteran has a much richer history than you might think! His journey is full of unusual twists and turns, quiet firsts, and a surprisingly strong cultural influence. What started out as just an ordinary dog in a newspaper comic strip gradually transformed this humble pup into a writer, pilot, dancer, budding student, mascot alongside astronauts, and a global brand. There’s much more to him than his red collar suggests, and we’re here to tell you his life story.
1. Snoopy did not make his first appearance on the first day of the "Peanuts" series
The "Peanuts" comic strip was officially published for the first time on October 2, 1950, but it wasn’t until October 4 that Snoopy made his first appearance in the newspaper. Although he appeared as early as the very first week of the series, he was not present in the actual first publication. The comic strip was initially published in seven newspapers before becoming one of the most famous comic strips in the world.
2. At first, he looked a lot more like a real dog
In the very beginning, Snoopy didn’t really act like the imaginative superstar that readers know and love today. When he first appeared, he walked on all fours and behaved more like an ordinary puppy. It’s hard to imagine today, but there was a time when readers didn’t expect much from this little guy.
3. Schulz was inspired by a real dog named Spike
Spike, Charles M. Schulz’s childhood dog, helped inspire Snoopy’s appearance and personality. (Thanks, Spike.) That doesn’t mean Spike didn’t make an appearance! Interestingly, Schulz later gave that name to Snoopy’s brother who lives in the desert—which is a great way to reuse the name.
4. Snoopy wasn't always Charlie Brown's dog
In the early “Peanuts” comic strips, Snoopy didn’t immediately take on his well-known role as Charlie Brown’s pet, even though it’s hard to imagine him any other way today. In the beginning, however, he was more like a stray dog belonging to the whole neighborhood than to any one child in particular.
5. His innermost thoughts changed everything in 1952
Snoopy’s first hilarious thought appeared on March 16, 1952. That single speech bubble paved the way for his personal opinions, his literary ambitions, and his meaningful adventures. Once readers were able to hear what Snoopy was thinking, he ceased to be just a dog and became one of the most memorable characters in comics.
6. His famous niche has arrived
Snoopy wasn’t always lying on the roof of his doghouse, raising his fist to the sky and battling his inner demons. No, that didn’t happen until later, and his first known appearance—in which he was sleeping on the roof—actually dates back to December 12, 1958.
7. He became a world-renowned author in 1965
Snoopy is a prolific writer—believe me! His career officially began in July 1965, when Schulz placed a typewriter on the roof of his doghouse. His famous opening line, “It was a dark and stormy night,” is taken from Edward Bulwer-Lytton, and Schulz used it to make Snoopy a delightfully stubborn aspiring novelist.
8. The aviation ace took flight in 1965
Snoopy has more than one title to his name, and that of World War I ace is just one of them. In fact, it was on October 10, 1965, that he first became a flying ace; in that dream, his doghouse had turned into a Sopwith Camel, and the Red Baron had become his greatest rival. The rest is history.
9. Joe Cool didn't appear until the 1970s
Listen, Snoopy is the kind of character who likes to reinvent himself from time to time, as readers have seen with his alter ego “Joe Cool.” He first appeared on May 27, 1971, as a student wearing sunglasses, after years of other transformations. The joke works because Snoopy pretends to be the kind of student who seems perfectly at ease at college, even though he’s just leaning against a wall.
10. Woodstock wasn't named right away
It’s hard to imagine Snoopy without Woodstock, but this adorable bird didn’t get his name until after he was created. Technically, Schulz didn’t give him that name until June 22, 1970, and the name is associated with the 1969 Woodstock music festival (as you can probably guess).
11. NASA actually used his name during the Apollo 10 mission
Snoopy made it all the way to the Moon—at least in name—even if his footprints didn’t stay there! During the Apollo 10 mission in 1969, NASA used “Charlie Brown” as the call sign for the command module and “Snoopy” as the call sign for the lunar module. The mission launched on May 18, and NASA’s official documents regarding Apollo 10 still refer to the lunar module by this nickname today.
12. “Snoopy Cap” was an actual nickname used at NASA
Speaking of NASA, the connection didn’t end with Apollo 10. The communication cap worn under the helmets during the Apollo era was also nicknamed the “Snoopy cap” because of its black-and-white appearance, which resembled Snoopy’s head and ears. NASA’s Silver Snoopy Award has also become a prestigious honor for employees who have contributed to improving flight safety and mission success.
13. It became a float in the 1968 Macy's Parade
You know you’ve made it when you officially take to the skies during the Macy’s Thanksgiving Day Parade. That’s exactly what Snoopy did, with his own fleet of balloons, back in 1968! That very first balloon featured him in his World War I flying ace outfit, which makes perfect sense since that character had already become one of his defining traits.
14. The name "Snoopy" was almost given to another dog
Believe it or not, Schulz originally wanted to name this now-famous dog “Sniffy,” but he realized that another comic strip was already using that name. He then remembered that his mother had once said that if the family ever got another dog, they should name it “Snoopy,” and it was that little memory that ultimately gave its name to one of the most recognizable comic strip characters.
15. Snoopy helped shift the Strip's center of gravity
Charlie Brown remained the emotional backbone of Peanuts, but it was Snoopy who propelled the comic strip into the realm of pure imagination. In the 1960s, he was everything at once: a novelist, a pilot, a lawyer—or whatever the gag called for. This versatility helped make him the face of the franchise.
16. Critics have criticized its commercial nature
Not everyone necessarily appreciates Snoopy’s adorable face. His popularity has even made him one of the most commercialized characters in American pop culture, and some critics have argued that this massive commercialization has made Peanuts far too ubiquitous compared to Schulz’s modest newspaper comic strip.
17. He has a star on the Hollywood Walk of Fame
Whether we like it or not, Snoopy’s meteoric rise to fame earned him the 2,563rd star on the Hollywood Walk of Fame on November 2, 2015. His star was dedicated in the “Motion Pictures” category and placed near that of Schulz himself.
18. Her personality is both sweet and bitter
Official documents about Peanuts note that Schulz described Snoopy’s personality as “a bit bittersweet,” which isn’t hard to notice as you read on. Schulz loved the fact that Snoopy could win, lose, become a hero, or turn into a disaster, all while taking refuge in the world of imagination when things went wrong. If you read the original comic strips, you’ll see that Snoopy’s funniest moments often have a softer side; he doesn’t just seek the spotlight—he faces the situation head-on.
19. He continued to publish "Peanuts" after Schulz's death
Schulz passed away in 2000, and the last Peanuts comic strip was published that same year. Snoopy, however, kept the show going, maintaining a public presence through television, merchandise, museums, books, and commemorative projects. And it’s not about to stop anytime soon! In 2025, Sony agreed to acquire an additional stake in Peanuts Holdings, bringing its share to 80%, while the Schulz family retained 20%.
20. He continues to win over new fans with his 1950s-style drawings
Snoopy’s longevity stems from his ability to seem both old-fashioned and contemporary. Sure, he’s been commercialized a bit, but he hails from a comic strip that debuted in 1950, and his little touches of confidence fit right in with today’s world. After more than 75 years of “Peanuts,” Snoopy remains one of the few characters capable of taking a nap in his doghouse while still reigning supreme.
