UPDATE: March has been rescued! Read the story here.

A dog doesn't get many signs that things aren't working out with his family.

One minute, it seems like things are going all right. There's food. Humans. Maybe even a loving caress here and there.

The next moment he's in the strange, steely environment of an animal shelter bombarded with bustle and noise. Yet achingly alone.

But it's hard for a dog not to recognize when he's being rescued from that place.

Like March.
