On a cold November night in Decatur, Georgia, a young Great Pyrenees named Casper faced the kind of danger livestock guardian dogs have been bred to confront for centuries.
He was not yet two years old.
Behind him were sheep that depended on him for protection. Nearby was Daisy, another Great Pyrenees who was only days away from giving birth.
In front of them was a pack of coyotes.
What happened next turned Casper from an ordinary working farm dog into a national symbol of courage and loyalty.
According to his owner, John Wierwille, Casper confronted a group of 11 coyotes that threatened the sheep he and Daisy were guarding in the early hours of November 4, 2022. By the time the violent encounter was over, eight coyotes were dead, the sheep had survived unharmed, and Casper had disappeared.
For two agonizing days, Wierwille did not know whether his dog was alive.
Then Casper came home.
His injuries were devastating. His tail had been badly damaged. His ears were torn. Large areas of skin had been ripped away, and deep wounds covered his body.
Veterinarians had difficult conversations with the family about whether treatment could save him.
But Casper survived.
After emergency veterinary treatment, multiple procedures and weeks of intensive care, the young guardian eventually recovered. More than a year later, Americans rewarded his extraordinary story by voting him the 2024 American Farm Bureau Federation’s People’s Choice Pup.
It sounds almost like the plot of a movie.
But Casper’s story is real.
A Guardian Named Casper
Long before the coyotes arrived, Casper had already demonstrated the temperament that made him suited to life as a livestock guardian.
His owner, John Wierwille, operates Ewe Can Do It Naturally, a Georgia business that uses sheep to help clear unwanted vegetation and invasive plants.
Instead of relying entirely on machinery to remove vegetation, the sheep can graze on properties around the Atlanta area.
But sheep need protection.
Predators do not disappear simply because the flock is working near an urban area.
Coyotes are a particular concern, and Wierwille relies on livestock guardian dogs to help keep his animals safe.
Casper was one of them.
He and Daisy arrived at Wierwille’s farm in 2022. Both were Great Pyrenees, a large working breed historically associated with guarding livestock.
Casper was named after the friendly ghost, an obvious reference to his thick white coat.
And despite the ferocity he would later display against the coyotes, people who knew him described an exceptionally affectionate dog.
Wierwille told the Georgia Farm Bureau that Casper was a “goofball” who loved other animals.
Chickens could sit on him.
He would approach sheep and rest his head on their backs.
When he first encountered Wierwille’s animals, there was little indication that this gentle white dog would soon become famous for one of the most dramatic livestock-defense stories in recent memory.
That combination of gentleness and protectiveness, however, is part of what livestock guardian dogs are expected to provide.
They do not exist to attack indiscriminately.
Their job is to live around livestock, recognize those animals as part of the group they protect and respond when a threat approaches.
Casper was about to face the greatest test of that instinct.
The Coyotes Arrive
The trouble began on the night of November 3, 2022.
Wierwille noticed coyotes near his Decatur property and attempted to drive them away.
For a time, it appeared to work.
But several hours later, during the early morning of November 4, the danger returned.
Wierwille heard his dogs barking.
When he went outside, he encountered a much more serious situation.
According to accounts Wierwille later gave to the Georgia Farm Bureau and The Washington Post, a group of approximately 11 coyotes was threatening the sheep.
Casper and Daisy immediately took on different roles.
Daisy remained close to the flock.
She had an additional vulnerability: she was heavily pregnant and only about nine days away from delivering puppies.
Casper moved toward the threat.
Several coyotes had entered the enclosure.
According to Wierwille, Casper attacked three of them inside the pen.
The encounter happened with startling speed.
But the confrontation did not end there.
When the remaining coyotes fled, Casper cleared a roughly four-foot hog-wire fence and pursued them.
Wierwille later told the Georgia Farm Bureau that Casper chased the animals through neighboring yards and carports.
