Histopathology of the tongue revealed severe multifocal necrotizing and suppurative subchronic inflammation. Streptococcus canis, Pasteurella multocida, and Staphylococcus pseudintermedius were isolated from the bronchoalveolar lavage and the oronasal fistula. Despite the treatment, the dog developed necrotizing fasciitis and the owners elected euthanasia.
