===Physical examination===

Physical examination is largely normal. Thoracic auscultation may reveal crackles or expiratory wheezes.

===Radiography===

===Radiography===

The most common radiographic finding is a diffuse ''Interstitial lung pattern'', a bronchial and/or alveolar pattern may also be visible. ''Eosinophilic Pulmonary Granulomatosis'' results in the formation of nodules, usually with indistinct borders. Consolidation of lung lobs and a hilar lymphadenopathy may also be seen.

==Bronchoscopy==

===Bronchoscopy===

Bronchoscopy may reveal increased amounts of mucous in the airways which may have a greenish appearance.  Tracheobronchial washes may show evidence of eosinophillic inflammation. Pulmonary specimens shouldbe carefully examined for the presence of infectious agents and for features of malignancy which may represent potential antigenic sources. Diagnosis may be complicated by the presence of a bacterial secondary infection resultng in a neutrophillic inflammation and a positiove culture on tracheal wash. Once the bacterial infection has been controlled, a second tracheobronchial wash may harvest eosinophils.

The prognosis is fair to good although there is a wide spectrum of disease severity. Some dogs require long term corticosteroid therapy. ''Eosinophillic Pulmonary Granulomatosis'' carries a guarded prognosis.
