Parents should know that this book might be upsetting to young children
The illustrations are beautiful, and the story is really engaging.
However, I shed some tears after I read it and I am 60 years old. It's quite a tribute to the writer and the illustrator that the reader cares so much for the dog and the frog and for their friendship. I would be careful about reading it to very young children. Parents should at least read it first and proceed from there.
