Code word courage

In September 1944, eleven-year-old Billie lives with her great aunt, Doff, eagerly waiting for her older brother Leo to return from boot camp, and desperate to find the father that left when she was little; but Leo brings a friend with him, a Navajo named Denny, and the injured dog they have rescued and named Bear--and when the two young men go off to war, Bear becomes the thread that ties them all together, and helps Billie to find a true friend.
