A very interesting case was admitted to Stange Memorial Clinic on April 9, 1952. It was a crossbred, 39 three-year-old Collie. The owner said that he had been listless and off feed, and that his right hind leg would drag at times. Most of the three years of the dog's life were spent in Galveston, Texas, according to the owner. The dog was depressed and auscultation revealed a pronounced heart arrhythmia.
