Barkley is a full-bodied Muppet dog who appears on Sesame Street. Barkley was originally called Woof-Woof when he first appeared in Season 9. In the 10th season premiere, the cast voted to rename him Barkley.
Barkley is energetic and playful, but is not anthropomorphized in the way that Rowlf and other characters are. While he may exhibit human-like emotions, he communicates only through barks, yelps, and physical contact. He was Linda's dog and understood the American Sign Language signs for "sit" and "stay." However, Barkley also had a close relationship with Big Bird. Indeed, in the 1993 book Imagine... Big Bird Meets Santa Claus, the large bird refers to Barkley as his dog. Although Linda has since moved on from Sesame Street, Barkley has remained, presumably becoming a ward of the community as a whole. The book A Bird's Best Friendshows that Granny Bird brought Barkley as a puppy for a present for Big Bird.
