This story, about Mrs May's lost puppy, is part of the "Wrens" level of story books at Stage 3 of the "Oxford Reading Tree". It is designed for children needing help to progress to Stage 4 and consolidates words from Stage 3 Wrens, in patterned sentence constructions. Other "Wren" stories in the series at Stage 3 include: role reversals of a knight; a princess and a dragon; Dad in pursuit of his musical hobby much to Floppy's consternation; a community help project to improve the environment; a strange creature which turns up in the park; Mrs May in great distress (but don't worry, there's a happy ending); and Mum and Dad experiencing the ups and downs of shopping together.
