Megaesophagus is a condition in which the oesophagus is dilated and lacks normal motility, preventing food from reaching the stomach and causing regurgitation, malnutrition, and life-threatening aspiration pneumonia in affected dogs.
Megaesophagus significantly impacts quality of life through persistent regurgitation, malnutrition, and aspiration risk. Affected dogs benefit enormously from owner commitment to upright feeding, frequent small meals, and close monitoring for respiratory signs. Bailey Chairs have transformed management for many dogs, enabling normal nutrition delivery. Aspiration pneumonia episodes are distressing and require prompt veterinary treatment with antibiotics and supportive care. Dogs with well-managed megaesophagus can have good welfare, though the condition requires lifelong vigilance. Euthanasia may be considered when aspiration pneumonia becomes recurrent and unmanageable despite best efforts.
