i remember when i was 6 and being able to read this book by myself so i wanted my grandson to be able to do the same thing. he loves books and is always reading them. some i think he's memorized cuz he can't do some of the words. because i sent the book to them i didn't read it. but i do know it's about comparisons. tall/short, wet/not wet, fast/slow, etc the dogs line up for a race to the big tree. it's a really nice surprise when you reach the tree at the end of the race.
