Among the female dogs Pluto serenades are some of his great loves, including his old one, Fifi the Pekingese, and his new one, Dinah the dachshund.
The song Pluto "sings" is "You Belong To My Heart" from the Disney feature film The Three Caballeros.' Additionally, when he is first listening to the radio in the music store, it plays an instrumental version of the song "Mexico" from the same film.
