Megaoesophagus causes regurgitation and aspiration pneumonia risk in affected dogs. Specialist feeding positions and food consistency can maintain acceptable quality of life.
Megaoesophagus dogs face chronic risk of aspiration pneumonia from regurgitated food entering the lungs — this is the leading cause of death in affected animals. The welfare burden falls heavily on owners who must manage every meal with precision. Dogs treated with appropriate postural feeding, appropriate food consistency and management of underlying causes can have acceptable quality of life, though the condition requires lifelong commitment. Sudden deterioration and aspiration pneumonia episodes cause acute suffering requiring emergency treatment.
