“This picture book has all the earmarks of a classic. There’s a plot that satisfies: as straightforward and cleanly shaped as, say, Harry the Dirty Dog or Corduroy. The text is spare—appropriately so, as the pictures are surpassingly eloquent. Not merely a showcase for the artist’s (considerable) prowess with watercolors, they say something. Overarching shape, knowledge of audience, small details—Simont gets it all right. This Stray Dog should find a home on library shelves and in readers’ hearts everywhere.” (Horn Book Magazine (starred review))
