A 6-year-old male Chow was admitted to the Stange Memorial Clinic on December 8, 1948, with a history of having suffered an injury of the left rear leg when struck by a car seven days previously. The dog was unable to walk on that limb, which was swollen from a point below the femoroltibial articulation up to the pelvic region. To facilitate examination, pentobarbital sodium was administered intravenously to effect, and the animal placed upon the table.
