Jackie: A Dog's Tale

What happens to a dog once it is adopted? Why does one adopt in the first place? Is the animal afraid? Does it fit in at home?
This is one dog's story.
Jackie, a year-and-a-half-old-dog, smart, sweet, cared for, now forgotten. How does such a thing happen?
I did some guessing and, from there, relate her true story to you.
Please enjoy her as much as I do.
