Did a dog really walk the whole Lewis and Clark expedition?
Yes. His name was Seaman, a Newfoundland bought in Pittsburgh in 1803 for twenty dollars, and he was the only animal to complete the entire journey to the Pacific Ocean and back. In this episode of Talking With Pets, Seaman tells the long walk himself: the night patrols, the swimming antelope, the buffalo he turned away from a sleeping camp, and the honest fact that nobody ever wrote down how his story ended.
History remembers the famous. Their pets remember the person. On Talking With Pets, a brown tabby cat named Prince MoRee runs a most unusual practice: he contacts the pets of history's greatest figures and lets them tell what they really saw. Tonight, a very large, very tired dog who walked from the middle of the country to the ocean and back, and stayed the whole time. True, surprising, and funnier than history has any right to be. Great for curious kids and the grown-ups listening with them.

From the episode
Roxie: (steady, not rushing) Wait. Go back. You turned a buffalo.
Seaman: I turned a buffalo. I am a very large dog and I was extremely motivated.
Roxie: (a small pause; letting it sit) That is a real thing you did.
[Prince MoRee makes a note, then underlines it.]
What's true, what we filled in, what we imagined
Every episode of Talking With Pets is built in three honest layers. Here is how this one breaks down.
Documented in the historical record
Seaman was a Newfoundland dog purchased by Meriwether Lewis in Pittsburgh in 1803 for twenty dollars, about half a month of a captain's pay. He accompanied the full expedition, which ran from 1804 to 1806, and was the only animal to complete the entire journey to the Pacific and back. The journals record his work: retrieving squirrels, geese, deer, and a swimming antelope for food, patrolling camp at night, and turning away a buffalo that charged through the sleeping camp. A beaver bit through his leg and cut an artery, and both captains cared for him until he survived. In 1806 he was taken on the return journey, and Lewis sent men to recover him. His name, Seaman, was established by historian Donald Jackson in 1984 from the Seaman's Creek place-name.
Grounded inference from the record
Seaman's reading of what he was for, that he was the one familiar thing beside a man who walked into the blank part of the map every morning, is a grounded inference from two documented years of a dog staying close to his captain. The journals name him many times; what the closeness felt like is the part we pictured.
Story, voice, and feeling
Seaman's voice, the séance, the maps drawn with a paw, the rivers named after snacks, the small captain hat, and the saluting fish are imagined, and the episode flags them as the story the dog made up. The episode is also honest about the one thing the record never says: what happened to Seaman after the expedition. Nobody wrote it down, so the show says we do not know.

Did a dog really go on the Lewis and Clark expedition?
Yes. Seaman was a Newfoundland dog purchased by Captain Meriwether Lewis in Pittsburgh in 1803 for twenty dollars, about half a month of a captain's pay. He traveled with the expedition all the way to the Pacific Ocean and all the way back, and he was the only animal to complete the entire journey. Source: National Park Service; the expedition journals.
What did Seaman do on the expedition?
He worked. The journals record him retrieving squirrels, geese, deer, and once a swimming antelope for food, patrolling the edge of camp at night, and turning away a buffalo that charged through the sleeping camp in the dark. Source: the Lewis and Clark journals; National Park Service.
Was Seaman ever hurt on the journey?
Yes. A beaver he was retrieving bit through his leg and cut an artery, and he nearly died. Both captains cared for him until he recovered. In 1806, on the return journey, he was taken, and Lewis sent men to recover him. Source: Lewis's journal; National Park Service.
What happened to Seaman after the expedition?
Nobody knows. The record simply stops, and the honest answer is that his fate was never written down. The episode says so plainly, because sometimes the brave thing is to say we do not know instead of making something up.
What is Talking With Pets, and is it good for kids?
