Hero Therapy Dogs explains what therapy dogs are and what they do. It was explained in easy to understand terms with several short sentences on a page. The book offers text features such as text boxes, an index, table of contents, glossary, and further reading. I felt that it jumped from the hospital to school to hospital again. It also dedicates a page to a specific dog, but there is only text on the page and there is not a picture of the dog. This is the only page without a picture and left me wanting to know what the dog looked like.
