Plain-English summary
A 16-month-old male King Shepherd and a 2-year-old female German Shepherd were both suffering from chronic regurgitation and diagnosed with megaesophagus, a condition where the esophagus is enlarged and doesn't function properly. During examinations, both dogs had white fungal plaques in their esophagus, and tests confirmed they had an infection caused by a yeast called Candida albicans. They were treated with fluconazole, an antifungal medication, which helped improve their condition significantly. If your dog has megaesophagus and isn't getting better, it might be worth asking your vet about checking for fungal infections.

Abstract
ABSTRACT Esophageal candidiasis is the most common cause of infectious esophagitis in human patients, but to date, this disease has not been reported in companion animals. A 16‐month‐old male intact King Shepherd dog and a 2‐year‐old female spayed German Shepherd dog were presented for evaluation of chronic regurgitation with diffuse megaesophagus identified on thoracic radiographs. In both cases, esophagoscopy disclosed diffuse, white fungal plaques, and brush cytology showed severe esophagitis with numerous yeast structures. Fungal cultures in both cases were positive for Candida albicans. The dogs were treated with fluconazole, which led to improvement or resolution of esophageal candidiasis. Esophagoscopy to evaluate for candidiasis should be considered in dogs with megaesophagus that either fail to improve on medical management or suffer an exacerbation of previously controlled signs.
