Dogs taste water.
Yes, water.
And in Dogs vs. Humans: A Showdown of the Senses by Stephanie Gibeault and Bambi Edlund you will learn not only this fact (well, see it again) you will see if humans can taste water, too. And if they can see the same as dogs, and if dogs smell the same as humans, and if dogs really can detect earthquakes. Plus, why do dogs line up the way they do for taking their morning, noon, and night relief walk. 
In this fun introduction on the way humans and dogs stack up against each other with their senses, it is filled with facts and humor. The senses dogs and humans are given, analyzed and we learn on a fun score card who wins each round. Such things as how dogs see better one way, but humans have seeing advantages in other areas, are the questions you explore. Each sense is given while sidebar facts are also there, with a few jokes as well.
The illustrations are cute, cartoon-like to help keep things light and fun. They were not my favorite part of things, but I did like how they keep things not too serious, but still educational. The best ages are probably 7 to 9, but you could go as young at 5 or 6, with reading help and/or reading to them. It could be a nice addition to a classroom, and even for the younger 10-11 year-old to help them have a starting point. But I would also feel that the younger images could be a turn off. However, overall this is a nice book and a good addition for libraries (personal, school and town).
Though available, I did read via an online reader.
