An eight‐year‐old, female, neutered labradoodle was presented for investigation of a three‐week history of lethargy and regurgitation. Two sets of conscious thoracic radiographs, performed approximately two weeks apart, revealed the presence of megaoesophagus. Serum cortisol concentration (pre‐adrenocorticotrophic hormone (ACTH) and post‐ACTH stimulation), serum aldosterone concentration post‐ACTH stimulation and plasma endogenous ACTH concentration confirmed the diagnosis of isolated glucocorticoid‐deficient hypoadrenocorticism. Following glucocorticoid supplementation, rapid resolution of the clinical signs was reported, and repeated conscious thoracic radiographs one week later showed complete resolution of the megaoesophagus.
