[Hypertrophic osteodystrophy of the dog (author's transl)]

The clinical and radiological findings of 21 dogs with hypertrophic osteodystrophy are described. In three cases a detailed pathologico-anatomic examination was performed also. The dogs concerned were young animals of large breeds with clinical symptoms of lameness, fever, pain, and thickened metaphyses of the long bones. Radiologically the condition was characterised by enhancement of the metaphyses and periosteal new growths of the bone. The pathologico-anatomic examination revealed a disturbed endochondral and periosteal ossification. Overnutrition as a possible cause of the condition is discussed.
