ABSTRACT
91 A 1-year-old spayed female Golden Retriever presents with a 1-week history of a productive cough, lethargy, mucopurulent nasal discharge, and hyporexia. She was adopted from an animal shelter 1 week prior to the development of clinical signs. Her vaccine history is unknown, but she was heartworm antigen-positive at the shelter. On physical examination, she is febrile (T:104°F), tachypneic (RR: 60), has bilateral mucopurulent nasal discharge, facial myoclonus, and hyperkeratosis of her foot pads and nasal planum. Harsh lung sounds diffusely and crackles in her right cranial lung field could be auscultated. No other abnormal findings were noted on physical examination. A left lateral thoracic radiograph is shown. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429401725/9d69b4ae-80d1-4f44-9dcb-659cda134065/content/fig91_2_C.jpg"/>
