I definitely wanted to check this book out since it's by Mem Fox, but I was surprised by the low ratings. Now that I've read it, I can see why some readers might feel uncomfortable with the rhythm. If you read it, you have to be deliberate about the rhythm you use, or it can feel clunky. And some people won't like all the repetition, but I think this makes it great for the youngest of readers.
However, if you sing the book to the tune of "Billy Boy," it works really well! Like many reviewers, I felt instinctively that there was some tune to go along with the words, but I couldn't quite put my finger on it. So I went looking online. Other reviewers here pointed me in the direction of "Billy Boy," and once I reacquainted myself with that song on YouTube, I enjoyed the flow of the book much more. I have to wonder if Mem Fox had that tune in mind as she wrote this. And if so, my only criticism is that it's not mentioned anywhere in the description to make it easier for people to discover.
The illustrations are nice and the dog's adventures make for a cute story. I know not everyone likes to sing, but I do, and I like to show parents this alternative way of reading books with their children, so I'm looking forward to using this in a future storytime.
