Readers similarly inclined to pick up hurt dogs on highways, but considerably younger than Maggie, 17, and her brother Paul and neighbor Mike, both 18, might go along with this humane little amenity about the trio on a camping trip with Fritzi, an abused sheep dog they find on the road, adopt, and heal. Mike especially, whose drinking parents have deprived him of a real family life, becomes attached to Fritzi; at the same time his feelings for Maggie change from brotherly to hesitantly romantic. Together, the four campers (Fritzi now one of the family) help find a lost child, get messed up with more drunks and a hippie-hating madman, meet other, nicer folks to balance out the bad, then stop at a ranch on the way home and realize to Mike's regret that this is where Fritzi belongs. But the return trip involves another hurt dog on the same highway. . . hence the title, which pretty well sums things up.
