Baskerville the Hound is a small, shaggy, brown dog with glasses and a pointed snout, who was originally created in 1962 as a foil for Rowlf in a series of Purina Dog Chow commercials. His name, which comes from the Sherlock Holmes novel The Hound of the Baskervilles, as well as his design were both originally considered for Rowlf. Like Rowlf, Baskerville made a single appearance in the first season of Sesame Street, but most of his further appearances were on The Muppet Show and related films, series, and specials.
