The authors give a detailed overview of osteochondroses of all clinically relevant regions such as shoulder, elbow, hip, knee and ankle, based on individual livestock as a pet or working dog and also from the point of view of the breeder. Each chapter contains information about the medical history, pathogenesis, diagnosis, treatment and prognosis of the disease. Many clinical case reports illustrate the presentation. Joe Morgan, a veteran radiologist, attaches particular importance to the radiographic diagnosis and shares his wealth of experience with the reader. Research reports from the Labrador Retriever provide valuable information on the impact of diseases in breeding and on meaningful control systems.
