The book is small and does have some useful information on Yorkies. However, I found the text to be more generic in the sense that it looks like the author copied a lot of the information from another generic dog book. Also, there were more errors in the text than there should have been for such a small book. For instance, on one page it mentioned how well a tick will show up on the dog's white coat. Yorkies don't have white coats. In addition, a lot of contradictory information was presented. In some parts of the text it mentions one thing while the boxes on the side said something else. To me the book was acceptable.
