Wienie, who might be the same character as Long Dog the Dachshund, is a semi-anthropomorphic dachshund who appears to have once been owned by Mickey Mouse.
Wienie is a long and bendy dachshund with a very pliable body. In the 1920's and 1930's, he was a friend and possibly pet of Mickey Mouse's, notably aiding him in the manufacturing of an airplane and in the management of a golf course.
Mickey also has a dachshund acquaintance known as Long Dog the Dachshund. Long Dog might be an alias of Wienie.
Behind the scenes
Wienie appeared in some cartoons and comic strips in the late 1920's and early 1930's. Notably, he appeared in the first-ever produced cartoon to star Mickey Mouse, Plane Crazy. He also appeared in the first-ever comic story to feature Mickey Mouse, Lost on a Desert Island, which is where he was referred to as "Wienie". The name "Long Dog the Dachshund" originates from the 1931 storybook, The Adventures of Mickey Mouse.
