How is the Vet Manual organized?

The Vet Manual is organized hierarchically by

  • Section (specialty area, eg, Circulatory System)
  • Chapter (eg, Anemia)
  • Individual Topic (eg, Hemolytic Anemia)

Specialty areas are listed in the Veterinary Content tab, located on the navigation bar at the top of every page and on the accordion menu at the upper left corner when browsing down a page. Veterinary content can be expanded to view its subordinate content.

Half of the Vet Manual's content is arranged into anatomic systems, and specific conditions are located in the system primarily affected. Conditions that may affect more than one system are covered in the section Generalized Conditions. The other half of the Vet Manual covers special topics or disciplines.

Content designed for pet owners, written in consumer-friendly language, can be found under the Pet Health and Wellness tab. The navigation bar allows you to access specific types of content: Quizzes and Cases, News, or, under the Resources tab, tables, images, calculators, and more.

What's the best way to find a veterinary topic in the Vet Manual?

  • Use the SEARCH bar at the top of each page (to search for a specific phrase, enclose it in quotes): “hemolytic anemia”
