This Atlas is surely the work with the largest number of photographs of sheep and goats ever published (more than 3,000), which makes it an indispensable anatomopathological and clinical diagnosis tool for professionals who work in the field with small ruminants.

The close collaboration, for more than 10 years, between prestigious Spanish and Iranian experts has made it possible to describe practically all of the common and emerging diseases that affect these species, without limiting it solely to the Western area, giving rise to a work of global interest that shares the long experience and deep knowledge of the team of authors.

The Atlas is structured into 12 chapters, taking into account the clinician's way of dealing with pathologies. In this way, there are chapters dedicated to the most important organic systems and apparatus, discriminating, when necessary, the conditions of young people and adults, and others are dedicated to the pathologies of animals of a certain age or sex, such as newborns or the females. Certain multisystem diseases, of relevant interest, are treated independently within some chapters.

Thus, the professional or student will be able to quickly relate the lesions and clinical signs detected in the farm with the photographs in the Atlas and the description of their clinical meaning, which will allow them to identify each lesion, contrast it with other similar ones and guide their diagnosis in a more precise way.

The COVID pandemic has proved the strong correlation between animal health, human health, and environmental health. Sheep and goat livestock movements from one area to another, globalisation, climatic emergencies and changes in human habits allow for many opportunities for diseases, including zoonosis, to spread. dr.Herriot is publishing this Atlas for the purpose of assisting veterinary professionals and students, as well as agronomists working with sheep and goats, in the faster and more effective diagnose of diseases all over the world.
