"On a cold winter day, a curious dog wanders onto a frozen river. Suddenly, the ice starts breaking up, and soon the dog is adrift and traveling - the unwilling passenger on a fast-moving sheet of ice.
The dramatic rescue of this little lost dog, who traveled seventy-five miles in two days, is a true story that will warm readers' hearts." (inside jacket cover)
This book will be appealing to young children even without knowing the history of Baltic, the Polish pooch found in 2010 on an ice floe in the Baltic Sea; though, if you're interested, the note from the author in the back of the book is a one page history of Baltic's travels and rescue.
According to the copyright page, "the art was done in watercolor, pen and ink on Fabriano hot-pressed paper". The text in the book is minimal - really no more than 2 lines per page, with predominantly simple words (other than the proper nouns like the name of the river Baltic got lost on - the Vistula) that can also be used for reader response.
Amazon recommends this book for ages 3 and up, but I think this could be a cute addition to any puppy storytime starting at 2 years old, so long as you don't have children who would get over emotional about a dog being lost and alone.
