3 year old Yorkshire Terrier

Discussion

Lung aspirates were taken and showed moderate to high numbers of nucleated cells, most of which were neutrophils with some lymphocytes. The pathologic diagnosis was moderate to marked mixed, primarily suppurative, inflammation with mild epithelial hyperplasia. An underlying infectious etiology was felt to be most likely, though no organisms were found on an extensive search. Fungal titres were negative.
The dog was treated with antibiotics and steroids, and improved greatly within two weeks. She is being weaned off steroids and monitored closely.
