The Junkyard Dog — Erika Tamar

Once Katie sees the skinny brown dog whimpering behind the junkyard fence, all she can think about is saving him. But Lucky doesn't belong to her, and even if he did, she couldn't bring him home -- dogs aren't allowed in the projects where she lives. Her mom and stepdad say she can feed Lucky, but only if she uses her own money and gets permission from the mean old junkman.

All this is hard enough. But when a brutally cold winter sets in, there's no time to lose. Lucky won't survive without some kind of shelter. And Katie's the only one who can save him.
