Rottweilers are a relatively healthy, disease-free breed. As with most large breeds, hip dysplasia can be a problem. For this reason, the various Rottweiler breed clubs have had X-ray testing regimens in place for many years. Osteochondritis dissecans, a condition affecting the shoulder joints, can also be a problem due to the breed's rapid growth rate. A reputable breeder will have the hips and elbows of all breeding stock X-rayed and read by a recognised specialist, and will have the paperwork to prove it.
