On August 20, 1969, a 9 1/2 year old spayed female German Shepherd crossbred dog was presented. The patient had the following anamnesis: The animal had been noticed to be lame in the hind quarters, particularly in the morning. The owner stated that the dog seemed to "warm out" of the lameness as the day went on. The dog had been sleeping more than usual the previous few days and acted very weak at times. There had been polydypsia, polyuria, and polyphagia for the previous few weeks.
