A nine-year-old male Irish Setter was presented at the Iowa State University Stage Memorial Clinic on July 28, 1966. The owner noticed that the dog had become listless and weakened about the first of July and had become progressively worse since that date. The animal was in a very weakened state and the mucous membranes appeared cyanotic.
