In late summer a farmer complains that some ewes have lost considerable condition as a consequence of not grazing and are observed frequently kicking at their heads with their hindfeet, causing serious damage to the poll and ears. The affected ewes seem distressed, frequently running 10–15 m then stopping, only to start running away again.

This seven-month-old, male German Shepherd Dog started to become acutely lame on its right forelimb 5 days ago. The dog was presented as an emergency because of acute exacerbation in this limb. On physical examination the dog had a rectal temperature of 103.6°F (39.8°C); he was reluctant to stand and was only toe touching with his right forelimb once he did stand; no obvious external trauma could be seen. Orthopedic examination revealed no obvious skeletal fractures. Deep palpation of the left proximal ulna and the shaft of the right humerus was painful. Radiographs of the right humerus were taken.
