It was minus 50 degrees. Winds screamed across the Bering Sea ice. In 1925, a small town in Alaska faced a literal death sentence. If you grew up watching cartoons, you probably think one dog, Balto, saved the day. Well, sort of.
The reality is way more complicated and, honestly, a lot more impressive than a Disney movie.
Nome, Alaska, was cut off. It was January. The ports were frozen solid. The only way in was by dog sled, a trail spanning nearly 700 miles of the most brutal terrain on the planet. This wasn't a race for a trophy; it was a race against diphtheria, a bacterial infection that was suffocating the town's children. They needed the antitoxin. Fast.
The Serum Run: Why We Still Talk About It
Most people call it the "Great Race of Mercy."
Basically, the governor of Alaska recruited the best mushers and the toughest huskies he could find. We're talking about a relay system. Twenty different teams. Over 150 dogs. They had to transport a 20-pound cylinder of life-saving serum from Nenana to Nome.
Usually, this trip took about 25 days. They did it in five and a half.
Balto, the Siberian Husky who led the final leg into Nome, became an overnight global sensation. He’s the one with the statue in New York’s Central Park. But if you talk to any serious sled dog historian or Alaskan local, they’ll tell you the name you really need to know: Togo.
Togo was the underdog. Literally. He was small, he was sickly as a puppy, and his owner, Leonhard Seppala, initially thought the dog wasn't fit for the sled. He actually tried to give Togo away twice. Togo jumped through a glass window to get back to Seppala. That’s the kind of dog we’re talking about.
The 260-Mile Push
While Balto got the cameras, Togo did the heavy lifting.

Seppala and Togo didn't just run a leg of the relay. They ran the most dangerous part. While most teams covered about 30 miles, Togo’s team covered 260. That is insane. They crossed the Norton Sound while the ice was cracking beneath their paws.
Visibility? Zero.
Seppala later admitted he couldn't see his own hands, let alone the trail. He relied entirely on Togo’s "sixth sense" to navigate the treacherous ice floes. If Togo had veered a few feet to the left or right, the entire team—and the serum—would have been lost to the freezing dark water.
Why Balto Got the Glory
It’s kind of a PR thing.
Balto was the lead dog of the team driven by Gunnar Kaasen. They were the ones who actually trotted into Nome at 5:30 AM on February 2, 1925. The townspeople were awake, waiting, and desperate. They saw Balto. They saw the serum.
The press went wild.
Kaasen and Balto ended up on a vaudeville tour. They did a short film. They were the face of the miracle. Meanwhile, Seppala and Togo—who had just performed one of the greatest feats of endurance in recorded history—were mostly ignored by the mainstream media at the time.
It’s a classic case of being at the finish line versus doing the marathon.

The Biology of a Hero
What makes these dogs different? It's not just "grit."
Siberian Huskies have a unique metabolism. They can burn calories in a way that defies most mammalian biology. They don't deplete their glycogen stores the way humans or other breeds do. They just... keep going.
Dr. Arleigh Reynolds, a veterinary surgeon and mushing expert, has spent years studying the physiology of these athletes. He notes that their ability to maintain aerobic capacity in extreme cold is unparalleled. They aren't just pets; they are high-performance machines.
But even the best biology can't explain Togo’s navigation. At one point during the 1925 run, the team was stranded on a moving ice floe. Seppala tied a lead to Togo and literally threw the dog across five feet of water to a stable piece of ice. The line snapped. Togo, according to accounts, grabbed the broken line in his teeth and pulled his team to safety.
You can't train that.
Life After the Run
The aftermath was a bit messy for the dogs.
Balto’s fame faded fast. He ended up in a "dime museum" in Los Angeles, which was basically a sideshow. He was neglected and kept in poor conditions until a businessman named George Kimble found him and raised money to bring the dog to the Cleveland Zoo. Balto lived out his days there as a hero, and you can still see his taxidermied remains at the Cleveland Museum of Natural History.
Togo lived a slightly quieter life.

He retired to Maine, where he sired a line of "Seppala Siberians." These dogs are still prized today for their working ability rather than their show-dog looks. Togo died at the age of 16, which is quite old for a dog that worked that hard. His coat is preserved at the Iditarod Trail Sled Dog Race Headquarters in Wasilla, Alaska.
The Modern Legacy: The Iditarod
If you’re wondering why we have the Iditarod today, it’s because of this event.
The race was established to commemorate the trail and the culture of mushing that saved Nome. Every year, mushers and their teams face the same elements—though with better gear—to honor the spirit of 1925.
It’s easy to look back and see this as a quaint historical story. But it was a pivotal moment in public health. It showed the world that vaccines and antitoxins were worth the effort, even if you had to drag them across the Arctic.
Correcting the Record
Is it fair to say Balto was a fraud? No. He still ran through a blizzard in pitch-black conditions. He still brought the medicine home.
But history is better when it's accurate.
- Distance: Balto ran 55 miles. Togo ran 260 miles.
- Difficulty: Togo crossed the Norton Sound ice; Balto ran a mostly inland trail.
- Leadership: Togo was 12 years old during the run—an "old man" in dog years. Balto was a young 6-year-old.
Actionable Takeaways for History and Dog Lovers
If you want to dive deeper into the real story of the dogs who saved Nome, skip the animated movies for a second and look at the primary sources.
- Read "The Cruelest Miles": This book by Gay and Laney Salisbury is the definitive account. It uses logs, letters, and interviews from the people who were actually there.
- Visit the Cleveland Museum of Natural History: Seeing Balto in person gives you a real sense of his size. He wasn't a giant wolf-hybrid; he was a compact, sturdy worker.
- Support Working Breed Rescues: Siberian Huskies and Alaskan Malamutes are high-energy dogs. Many people adopt them because of the movies and then realize they can't handle the exercise requirements. If you love the story, support the breeds by helping rescues like the Siberian Husky Rescue/Referral of California (SHRR) or similar local groups.
- Explore the Seppala Siberian Sleddog Project: Learn about the lineage Togo left behind. These dogs look different from the fluffy huskies you see at the park; they are built for the trail.
- Check the Serum Run Records: The Alaska State Library holds digital archives of the telegrams sent during the 1925 crisis. Seeing the desperation in the text—"NOME CALLING... SHIP SERUM"—makes the dogs' achievement feel much more visceral.
The 1925 Serum Run wasn't just about one dog. It was a massive logistical miracle powered by paws and human stubbornness. While Balto got the statue, Togo and the other 148 dogs provided the muscle that kept a town from disappearing.
