It’s a straightforward text for young readers that provides the basics of how seeing-eye dogs are trained and what kind of services they provide.  It explains for children that when such a dog is in its harness it is in work mode, and they should not attempt to pet or play with it.  It describes some of the commands dogs learn, as well as some cues they may give to their owner.  Because it is a text intended for young readers, the depth of information is somewhat limited, as there are only a few sentences, in large font, per page.  The text on each page is supported by full-color photos on the opposing page.  The book contains all your basic non-fiction text features, including table of context, index, etc. I wish they had kept with the more traditional academic vocabulary of “Glossary,” instead of “Words to keep” though.  Also, although there is another book in this series dedicated to other service animals, I thought it would have been nice in this book to include a sentence or two explaining that Guiding for the blind is only one type of service dogs (and other animals) have been trained to do.
