No Songs for Dogs

    'No Songs for Dogs' will make an intriguing title for a story. Trouble is, I have no idea what the story should be about.
    I can conjure up some nebulous designs. One, a post-apocalyptic world in which dogs are diseased; one boy has a dog companion whom he fights to save from the law -- and the dog fights to save him. Two, gene-modded dogs that are near human but have no rights; humans are buried with hymns, dogs no. Three, 'o' is the only vowel used; the title is a cypher for a clandestine operation.
    So, Gentle Reader, I ask your help please. Which of the nebulous designs above do you prefer? Or will you suggest another?
    Who is the hero?
    What is at stake?
    Where does the action happen?
    When?
    Why?
    How? Well, that's the story, isn't it?
