The trouble is, those days have been piling up fast for Diamond.
When she was 3 years old, her owner and best friend died. Despite that tragic turn, she was in her prime - a buoyant, loving dog with her whole life ahead of her.
Little did anyone know at the time that Diamond would spend the next five years at the West Virginia shelter.
Now, she's a senior dog, her hopes of finding a real home dwindling with each day.
Even if she never shows it.
