The Heartwarming Stories Of 11 Of History’s Most Loyal Canine Companions

From the English Pointer who won a medal for her heroism during World War II to the Newfoundland who accompanied the Lewis and Clark expedition, these brave dogs made a furry mark on history.

On September 11, 2001, Roselle the guide dog was taking a nap under her owner’s desk on the 78th floor of the World Trade Center when terrorists flew an airplane into the North Tower. Roselle quickly got to work, leading her owner and his office to safety below. She even navigated him into a subway station as the air grew thick with smoke and debris.

For this, Roselle was awarded for her bravery. But she’s just one of many famous dogs in history who accomplished extraordinary feats.

There’s Balto, who helped save the town of Nome, Alaska, during a diphtheria outbreak; Zanjeer, the Indian bomb-sniffing dog whose work prevented greater catastrophe during the 1993 terrorist attacks in Mumbai; and dogs like Judy and Sergeant Stubby who fearlessly stepped up during wartime. There are also dogs like Greyfriars Bobby and Hachikō, who became famous simply due to their undying loyalty to their owners.

Read on to learn the stories of 11 famous canines, from the real dog behind Toto in The Wizard of Oz to Buddy, the first American seeing eye dog.

Balto, The Famous Dog That Saved An Entire Town

In January 1925, disaster came to the small town of Nome, Alaska, in the form of a deadly diphtheria outbreak. People had started to die, and the town’s 1,400 residents desperately needed a serum to stave off a catastrophe. But with the ports blocked by ice and planes grounded by winter weather, there was only one way the serum could get there: by sled. Before long, one intrepid dog named Balto became a national hero.

Born around 1919 in Nome, Alaska, Balto was a black Siberian husky with a distinctive white leg. During the 1925 Serum Run, Balto was tasked with leading the final 54-mile leg of the 674-mile route alongside his musher, Gunnar Kaasen, and another dog named Fox.

Though they were the last of the sled teams to embark on the six-day mission, Kaasen, Balto, and Fox faced extreme conditions as they carried the life-saving serum toward Nome. Temperatures plunged to -40 degrees Fahrenheit, and a harsh wind created whiteout conditions that Kaasen could hardly see through. At one point, his sled even flipped, which meant that Kaasen had to dig through the snow with his bare hands to recover the precious antitoxin package he was transporting.

On Feb. 2, 1925, Balto and his team finally arrived in Nome and delivered the serum to the town’s residents. “Damn fine dog,” Kaasen said of Balto.

For Americans across the country who had followed the harrowing story on the radio, Balto quickly became a national hero. But not everyone saw Balto that way — including his breeder Leonhard Seppala.

Seppala had also participated in the 1925 Serum Run with another of his dogs, Togo. He thought the praise lauded on Balto was unfair because Balto had co-led the final leg with Fox and because Togo had covered more miles over rougher terrain. Togo ran 261 miles, whereas Balto ran just over 50 miles.

As such, Seppala believed that the praise for Balto was overblown, and he didn’t think that Balto deserved to have a statue erected in his honor in New York City’s Central Park. (Today, Togo also has a statue, albeit a smaller one, in the city’s Seward Park.)

“I hope I shall never be the man to take away credit from any dog or driver who participated in that run,” Seppala said in his memoir. “We all did our best. But when the country was roused to enthusiasm over the Serum Drive, I resented the statue to Balto, for if any dog deserved special mention it was Togo.”

It can be agreed today, however, that Balto, Togo, Fox, and all the other dogs who participated in the 1925 Serum Run played a heroic role in delivering life-saving medicine to a desperate town.

Zanjeer, The Indian Bomb-Sniffing Dog Who Saved Countless Lives

Zanjeer The Dog

Like Balto, the next famous dog on our list was a national hero. During his career with the Mumbai Police Bomb Detection Squad, Zanjeer the Labrador Retriever helped detect guns, over 240 bombs, 600 detonators, 250 hand grenades, 7,340 pounds of the explosive RDX, and 6,000 rounds of ammunition.

The chief of the unit, Nandkumar Choughule, later said that Zanjeer was “god sent.” And at no time was this more true than during the harrowing 1993 terrorist bombings in Mumbai.

In December 1992, the same month that one-year-old Zanjeer started working for the Mumbai Bomb Squad, a right-wing Hindu organization tore down the sacred Babri Masjid mosque in Ayodhya, India. The destruction of the mosque triggered riots and resulted in the deaths of as many as 2,000 people.

In response, an underworld Muslim crime syndicate known as D-Company started planning bombings across Mumbai. Zanjeer swiftly got to work with his human and canine colleagues to track down the explosives. With his three-bark alert, Zanjeer notified his handlers of rifles, pistols, grenades, suitcase bombs, RDX explosives, and gelatin sticks. Though the 1993 Mumbai bombings took hundreds of victims, Zanjeer’s work saved countless lives.

The dogged investigator continued his work even after the threat in Mumbai had waned. Zanjeer maintained his job as a bomb-sniffing dog over the next several years and detected hundreds more weapons.

When Zanjeer died at the age of eight after a struggle with an illness that may have been bone cancer or lung failure, his human handlers were determined to give him a hero’s sendoff.

“Policemen who die a martyr’s death get accolades, but canine members go unnoticed,” local labor leader Dilip Mohite told Mid-Day.

The bomb-sniffing dog was thus honored with a state funeral in recognition of the lives he’d saved.
