Summary
The clinical and radiological findings of three related Miniature Poodles with multiple
enchondromatosis (Ollier’s disease) are presented. Persisting, in part ossified growth
plate cartilage foci were found bilaterally in the humerus, radius, ulna, femur, tibia
and fibula of each dog and in one dog in some metacarpal and metatarsal bones. The
ribs and many vertebral bodies were also affected. There was evidently no bone formation
in the sternebrae. All three dogs first attracted attention at the ages of four to
six months, with spontaneous bilateral femoral neck fractures. The mode of inheritance
of the condition is not yet clear, but based on the known pedigree data a dominant
effect appears unlikely.
