Homer & Jethro once did a parody of Patti Page's "How Much is That Doggie in the Window," to wit:

    "How much is that hound dog in the window,
    With the basketball nose on his face?
    You know what a basketball nose is,
    It dribbles all over the place..." etc., ad nauseum

I also once heard a version of "Rex, The Piddling Pup" set to music. Any takers?
