Preposterous just lies around and doesn't do anything; he doesn't like to bark or play. Sometimes he would even attack Oscar.
The dog also appeared in various scenes in Follow That Bird and The Adventures of Elmo in Grouchland. The puppet was later modified into Oscar's pet cat, Fido, in "Elmo's World: Cats." He also appeared in the View-Master Interactive Vision video, Let's Play School, as a pet of one of the Grouchketeers and named Junkyard.
