When you think of science fiction, you probably picture sleek starships, androids wrestling with morality, or dystopian futures filled with neon rain. But let’s be honest—no story feels complete without a dog. Loyal, brave, occasionally hilarious, dogs in science fiction remind us that even when humanity ventures to the stars, we still want a wagging tail by our side.
From genetically modified canines to faithful Earth-born companions, sci-fi dogs aren’t just background pets. They’re often symbols of loyalty, emotional anchors for human characters, or even full-blown heroes in their own right. So, let’s explore some of the best and most interesting dogs in science fiction across books, comics, movies, and television.
1. Laika (Based on the Real Dog, Reimagined in Sci-Fi)
The real Laika, the first living creature to orbit Earth, has inspired countless works of science fiction. Many writers and filmmakers have imagined alternate timelines where she survived, became enhanced, or even returned to Earth with cosmic powers. In comics like Laika by Nick Abadzis, her tragic real-life mission is reimagined with heart and poignancy, making her a symbol of both human ambition and the costs of exploration.
2. Krypto the Superdog (DC Comics)
If Superman gets to have superpowers, why shouldn’t his dog? Krypto, first appearing in Adventure Comics in the 1950s, has all of Superman’s abilities: flight, heat vision, and, presumably, the ability to chase balls at supersonic speeds. Over the decades, he’s appeared in animated shows, comics, and even video games, always reminding us that a loyal dog is still man’s best friend—even if that man is the Last Son of Krypton.
3. Einstein (Back to the Future)
The first time-traveling dog! Einstein, Doc Brown’s lovable sheepdog, might not have spoken or flown around with a cape, but he did hold the honor of being the world’s first temporal test subject. In Back to the Future, Einstein gets sent one minute into the future, proving the DeLorean time machine works. That’s one brave pup—and honestly, he deserves way more credit for making Marty McFly’s adventures possible.
4. Porthos (Star Trek: Enterprise)
Captain Jonathan Archer’s beagle, Porthos, is easily one of the most beloved pets in Star Trek. Whether stealing cheese from dignitaries or curling up in Archer’s quarters, Porthos reminded us that humanity brings more than just technology into space—we bring the comforts of home. One episode even revolved around his illness, making the stakes of space exploration feel more personal and relatable.
5. Bandit (Jonny Quest)
Though Jonny Quest leans more toward adventure than hard sci-fi, Bandit the dog earns a spot for being the perfect comic relief in a futuristic, gadget-filled world. His expressive face and antics broke the tension of otherwise serious plots, proving that dogs could thrive even in stories about lasers, secret organizations, and strange new worlds.

6. Blood (A Boy and His Dog by Harlan Ellison)
One of the most unusual and unsettling canine characters in science fiction is Blood, the telepathic dog from Ellison’s A Boy and His Dog. Set in a post-apocalyptic wasteland, Blood communicates directly with his human partner, Vic. Their relationship is both dark and fascinating, exploring survival, dependence, and the uneasy balance between humanity and morality when civilization collapses. Definitely not your average good boy, but one of the most memorable.
7. Samantha (I Am Legend)
Okay, she’s not genetically modified or telepathic, but Samantha, Robert Neville’s German Shepherd in I Am Legend (especially in the Will Smith film adaptation), might be the most heartbreaking dog in sci-fi. In a world overrun by vampiric mutants, Sam provides Neville with not just protection but emotional grounding. Her fate is one of the most devastating moments in science fiction cinema. If you didn’t cry, check if you’re secretly a robot.
8. Dug (Up)
Yes, Up is technically a Pixar movie about balloons and adventure, but Dug is absolutely a sci-fi dog. He wears a collar that translates his thoughts into speech—finally fulfilling every dog owner’s dream of hearing, “I love you!” in plain English. Dug proves that even with futuristic technology, dogs will still be goofy, loyal, and obsessed with squirrels.
9. The Dog in Doctor Who (K-9)
K-9, the robotic dog introduced in Doctor Who, is the perfect blend of loyalty and technology. Armed with lasers, vast databases of knowledge, and an adorably clunky design, K-9 accompanied the Doctor on several adventures. He’s more than just a gadget; he’s proof that even in the farthest reaches of time and space, we can’t help but build robotic versions of our best friends.
10. The Mutant Dogs in Resident Evil
On the scarier side, we have the zombie-like Dobermans from Resident Evil. These bioengineered nightmares are loyal only to chaos, showing the darker side of dogs in science fiction. While they may not warm your heart, they demonstrate how easily humanity’s meddling with genetics can twist even our most loyal companions into terrifying monsters.
Why Dogs in Science Fiction Matter
Dogs in science fiction aren’t just cute add-ons—they’re essential storytellers. They symbolize loyalty in hostile worlds, bring levity to tense narratives, and sometimes challenge our morality in unexpected ways. Whether genetically engineered, robotic, or just plain normal, these dogs remind us that no matter how far humanity travels, we’ll always crave the companionship of a furry friend.
Because let’s face it: exploring the galaxy is cool, but exploring it with a dog? That’s unforgettable.
