While giving exact statistics, the interpretation is such as to gloss over the difficulties entailed in getting into Veterinary School. The author plays fast and loose with language, switching from students to applicants, never giving the number who actually make it into that first class. As a better source, check the book on admission requirements.
The chapter on the history of veterinary medicine is specious, spurious, highly imaginative, and anachronistic. Check the Oxford Classical Dictionary if you're really interested and want the facts.
The rest of the book is, as your blurb says, pretty complete and up to date. I think deciding to become a Veterinary Technician after two years at an unaccredited school earning $17,000 a year in order to play with kitties and puppies is a total waste of time. Go find a different profession, earn a decent living wage, leave the door open so you can transfer a 2-year-degree to a 4-year-institution 20 years from now, and with your increased earning power, indulge your madness of kitties and puppies on the side.
Considering there is nothing much else with hard information available, the book is worth a read. Buy it in conjunction with the Admission Requirement book, read statistics carefully, and it will be enlightening.
