This bitch had an ovariohysterectomy at the Stange Memorial Clinic in December 1972 when she was 6 months old. She went home apparently normal. She was presented at the clinic on March 24th, 1973 because she was vomiting and depressed. She had been seen ingesting a leather glove and some hay. Radiographs made at this time showed an acute intestinal obstruction.
