1931 was a year rife with superstition and subtle, supernatural beliefs. One such belief involved a dog, whose owner claimed could display psychic powers. Missouri professors sought to expose what they assumed had to be a hoax. Armed with a myriad of tests and veterinarian assistance, they set their sights on an allegedly psychic pup named Jim. 

After the tests, the professors made a surprising conclusion, one that remains an unforgettable aspect of Missouri history. Jim the Wonder Dog, these professors announced, possessed an occult power.

This is the story of a Llewellyn setter who could allegedly perform a number of clairvoyant tasks, including responding to commands in Morse code. It’s a story that remains in American folklore and unresolved mystery files to this very day. Let’s dive into the psychic details of Jim the Wonder Dog, a celebrity pup who once called Missouri home.

The Beginnings of Jim’s Clarivoyant Abilities

Jim was born on March 10, 1925, and was the last of seven pups from a litter of pureblood champion Llewellyn setters bred in Louisiana. He was reportedly the runt, preferring to sit in the shade and watch other dogs train instead of participating himself. His breeder even considered putting him down, given Jim’s refusal to train and maintain a healthy weight. 

Instead, the pup was given away as a gag gift to Sam Van Arsdale, an avid sportsman and hotel manager in West Plains, Missouri, who had purchased better dogs from the breeder before. While Jim’s litter mates went for $25 apiece, the runt of the litter arrived at Van Arsdale’s door for free.

Jim’s breeder was only the first person to think him difficult; the dog trainer Van Arsdale hired also found him impossible. Despite being a purebred hunting dog with a fine lineage, Jim refused to perform any of the activities needed by hunting breeds, which is why even Van Arsdale considered giving him away. However, one hot afternoon in the training field, Jim proved he was going to make an impression beyond his breed. 

Tired and sweating, Van Arsdale spoke aloud that he wanted to rest under a hickory tree. Jim, without prompting, proceeded directly to the nearest hickory and sat down, which was of course one of his favored activities. Van Arsdale assumed this was happenstance, until he tested it. He asked Jim to go to a walnut tree, followed by a cedar, a stump, and even a tin can. Jim went and arrived accurately at each item, without hesitation. But how?

Jim’s Predictions and Growing Fame

Over the next several years, Jim performed multiple demonstrations that defied explanation. According to the Missouri Secretary of State’s office, Jim could identify a specific car on a street if given only the license plate number, either written or spoken aloud. He could also pick out strangers from crowds when given vague descriptions, such as “the man who sells hardware” or “the visitor from Kansas City.” 

Jim reportedly responded to commands in Italian, French, German, Spanish, and Greek, despite the fact that Sam Van Arsdale spoke only English. He could also parse instructions written in shorthand and respond to directions communicated in Morse code, of all things.

As Jim aged, he grew into his hunting dog pedigree, and Van Arsdale was meticulous about keeping track of his hunting record. His owner stopped counting birds after Jim flushed at least 5,000, a total no other dog had matched in this era. Outdoor Life magazine named Jim “The Hunting Dog of the Country,” despite hunting being the least remarkable thing about him.

Audiences began asking Jim to predict futures, and Van Arsdale would write options on slips of paper, asking Jim to select the correct one. The dog was reportedly right every time, regardless of the contents of the predictions. He was even right about the Kentucky Derby, and more than once. Beginning in 1930, Van Arsdale asked Jim to pick the winner; according to records from the University of Missouri’s CAFNR, Jim chose correctly seven years in a row.

“Jim could do everything,” said Frank Schloegel, a modern-day Jim enthusiast, “and nobody knows about it.”

The University of Missouri Tests Jim

Van Arsdale brought Jim to the University of Missouri in 1931, more curious about his dog’s abilities than anything else. Jim was examined by Dr. A.J. Durant, the chair of veterinary science and one of Missouri’s most respected scientific minds in his field. Durant fully expected to expose Jim’s demonstration as tricks, too much of a scientist to believe otherwise. 

He invited Dr. Sherman Dickinson from the College of Agriculture, psychiatrists from Washington University in St. Louis, foreign language faculty, and a crowd of students and staff to the Mizzou Quadrangle to watch Jim’s tests. And it was an incredibly thorough process, reports indicate.

Durant began with a thorough physical examination that revealed Jim was essentially a normal Llewellyn setter, with a few exceptions: a wider than normal span across the brow, a greater distance from brow to the top of the skull, and notably large eyes. Multiple reports and records state that Jim had large, piercing, human-like eyes, though it’s difficult to ascertain whether his reputation for human predictions influenced this interpretation.

After his physical exam, the testing began. Van Arsdale was told not to move during the experiments, though he was still allowed to observe; however, scientists wanted to ensure he wasn’t influencing his pup. A line of language professors stepped up, asking Jim to identify various people and objects in their preferred languages. The dog was successful in every attempt.

The baffled professors were not able to identify anything that pointed to Jim’s abilities, no secret cues or signals given by Van Arsdale. When Durant and the others discussed their findings, they concluded their inability to offer a conventional explanation. Durant delivered the professors’ verdict: Jim possessed an occult power that might never come again to a dog in many generations.

In later years, Durant was asked whether he had been joking or humoring Van Arsdale when he announced Jim’s abilities. He maintained that his conclusion was true, that the world was blessed with a clairvoyant dog.

Jim’s Rise to Unconventional Fame

Word of Jim’s University of Missouri examination spread quickly, and even politicians grew curious about this humble dog. Jim was summoned to perform before a joint session of the Missouri State Assembly, identifying specific lawmakers when asked, and even obeying an instruction communicated in shorthand. Jim also responded correctly to a Morse code communication, stunning everyone in attendance.

He also performed elsewhere, including at the Missouri State Fair in Sedalia, again for the Missouri Legislature, for Ripley’s Believe It or Not!, and at the Kemmerer Hotel in Wyoming. Following this particular performance, the Kemmerer Gazette published a piece formally dubbing him “The Wonder Dog”.

Hollywood was also a factor in Jim’s life: Paramount Pictures made Van Arsdale an estimated offer of somewhere between $364,000 and half a million dollars for a year-long movie contract. However, Van Arsdale declined the offer, along with several others, refusing to allow Jim to be used for product promotion or entertainment. He remained, to the end, more interested in understanding Jim than profiting from him, having never charged for a single demonstration or endorsement.

Theories and the Unexplained Aspects of Jim the Wonder Dog

The most famous case of an apparently gifted animal like Jim is Clever Hans, the German horse who appeared to solve arithmetic problems, but was actually reading unconscious physical cues from his handler. Known as the Clever Hans effect, it is the first explanation most skeptics opt for when considering stories like Jim’s.

However, this explanation doesn’t necessarily work, given how the experiments were designed. Van Arsdale was restrained from moving during many of the university demonstrations, and his inability to speak or gesture did nothing to slow Jim down. Plus, Jim’s future-oriented predictions could not be explained by reading a handler’s cues, as it’s not as if his owner knew which horse would win the Kentucky Derby.

A bronze tablet beneath Jim’s statue in Marshall reads, “The fact that he was able to predict the outcome of future events seems to indicate that he possessed psychic power.” It became a fact that no one could refute, despite how impossible it sounded.

The Wonder Dog’s Passing and Legacy

On March 18, 1937, Van Arsdale loaded Jim into the car for a fishing trip, but his pup collapsed shortly after their arrival. Van Arsdale drove as fast as he could to the Sedalia Animal Hospital, but Jim passed away at twelve years old.

Jim’s obituary ran in newspapers as far away as Canada, and the Van Arsdale family received more than 500 correspondences of condolence. They asked that Jim be buried in their family’s plot at the Ridge Park Cemetery in Marshall, but the cemetery board refused, as they don’t allow dogs to be buried in their plots. 

In an act of defiance, Jim was buried just outside the fence, following Van Arsdale’s refusal to give the University of Missouri Jim’s brain for study. As the cemetery expanded, the fenceline and boundaries moved. Jim is now inside Ridge Park Cemetery, surrounded by the graves of Marshall’s human citizens, and his grave is the most visited in the cemetery, based on the offerings constantly placed there.

The Friends of Jim the Wonder Dog organization has preserved this history and continues to host Jim the Wonder Dog Day each year in Marshall. “What the University of Missouri concluded that day wasn’t speculation—it was the considered opinion of scientists who came specifically to disprove what they saw,” the organization’s representatives stated, “They could not. And Dr. Durant never backed away from what he said, for the rest of his life.”

Today, the Jim the Wonder Dog Museum and Garden now occupies the site of the old Ruff Hotel, where Jim lived with the Van Arsdale family and performed impromptu demonstrations in the lobby. A bronze statue of Jim also stands in the garden, welcoming visitors from across Missouri and beyond. Should you choose to visit, think of Jim and his remarkable abilities, a psychic power left unexplained for decades.
