Big Bird and Barkley in Japan

Barkley, originally named Woof-Woof, was a dog character on the children's television program Sesame Street.

Introduced in the less-than-successful A Special Sesame Street Christmas, its original actor Toby Towson notes that Barkley was originally intended to be an acrobatic ape.

Owned by deaf librarian Linda, the character made its formal television debut in the tenth season of the show. Its name changed in the coming episodes from "Woof-Woof" to "Barkley". It is of note that producers and Towson spelt the original name "Woov-Woov".

Around this time, Towson's contract ran out, and Bruce Connelly replaced him.

Barkley is essentially gone from the show now, having not appeared in the past few seasons.
