Seaman

Seaman, a Newfoundland dog, was a member of the Lewis and Clark Expedition, the first trip from the Mississippi River to the Pacific coast and back. He was the only animal to complete the entire three-year trip. Seaman was purchased in 1803 specifically for the expedition by Captain Meriwether Lewis, while he was in Pittsburgh, Pennsylvania, awaiting completion of the boats for the voyage. He chose a Newfoundland, whose estimated weight is and for which he paid the high price of $20 (): half a month's pay for an Army captain. Working dogs, strong and easy to handle—Lewis describes Seaman as "docile"—, he chose a Newfoundland because they do well on boats, are good swimmers, and can assist in water rescues. His name reflects this. There is no explicit description of Seaman's color or appearance. He is nowadays universally depicted as black or dark brown, the colors of most modern Newfoundlands, but a survey by an art historian of the breed as it was depicted in paintings of the early nineteenth century found "not a single all-black [that] was called a Newfoundland". "In fact, all the early 19th century illustrations which I have found, and whose color I could authenticate[,] were white with black or dark areas and frecklings." Seaman on the expedition Seaman did many things to help the explorers, and they became fond of him. He was "our dog".
