Megaoesophagus causes regurgitation and aspiration pneumonia risk in affected dogs. Bailey chairs, upright feeding, and careful dietary management significantly improve quality of life.
Megaoesophagus causes significant welfare challenges. Affected dogs experience repeated regurgitation, which is distressing, and the constant risk of aspiration pneumonia creates both welfare and clinical management burdens. Without appropriate management, the quality of life is poor and aspiration pneumonia episodes are frequent and potentially fatal. With appropriate management — Bailey chairs, correct diet consistency, upright feeding — many dogs maintain good quality of life for years. The management is intensive, requiring owner commitment to multiple daily postural feeding sessions. The underlying cause must be investigated as treating myasthenia gravis, for example, can resolve the megaoesophagus entirely.
