And you should have it before you need it--as in, before you animal is sick. This is a complete and well done reference guide for those of us who don't need to know the vet manual's textbook explanations and can't afford to own those massive volume collections anyhow. It covers basic diagnosis, examination, equipment, internal and external parasites, medicines, dosages, tips for treating, how to administer meds to differnt types of animals, hygiene information, and, best of all to help your vet out, it contains photographs of microscope slides of what the nematoads or protozoans will look like and sketches of them for identification of relative size.
If you don't have an exotics or herp vet near you, this will help your furry pet vet help your herp. Believe me, I am thankful every day that I got this book when I didn't really need it because it meant the small town horse and dog vet clinic could see my old world chameleon and HELPED me, like they would not have been able to without this book.
