<Li> Dallas McKennon as Toughy, a stray male mutt from the dog pound . He speaks with a slight Brooklyn accent, like Peg . McKennon also voiced Pedro, a stray male Chihuahua from the dog pound who speaks with a Mexican accent; a professor, and a laughing hyena . </Li> <Li> The Mellomen (Thurl Ravenscroft, Bill Lee, Max Smith, Bob Hamlin and Bob Stevens) as Dog Chorus </Li> <P> In 1937, Disney story man Joe Grant came up with an idea inspired by the antics of his English Springer Spaniel Lady, and how she got "shoved aside" by Joe's new baby . He approached Walt Disney with sketches of Lady . Disney enjoyed the sketches and commissioned Grant to start story development on a new animated feature entitled Lady . Through the late 1930s and early 1940s, Joe Grant and other artists worked on the story, taking a variety of approaches, but Disney was not pleased with any of them, primarily because he thought Lady was too sweet, and there was not enough action . </P> <P> In the early 1940s, Walt read the short story written by Ward Greene, "Happy Dan, The Whistling Dog", in Cosmopolitan magazine . He thought Grant's story would be improved if Lady fell in love with a cynical dog character like the one in Greene's story and bought the rights to it . The cynical dog had various names during development, including Homer, Rags, and Bozo, before "Tramp" was chosen . </P>
