"Landfill Dogs tells the stories of homeless dogs who will be killed if they aren't adopted. Instead of shooting them at the shelter, however, Shannon takes them to a municipal landfill site.
Most obviously, this is where the dogs will end up if they don't find a home, trash buried among other discarded possessions. More subtly, county animal shelters are managed by the same government department as landfills, suggesting, as Shannon says, that "homeless cats and dogs are just another waste stream." Homeless animals at picturesque landfill sites also represents the idea of trash transformed into beauty: animals on death row reveling in play and affection, buried garbage a breathtaking background."
