In general, dogs with megaesophagus cannot be cured but are rather managed. There are certainly exceptions to this and I and my holistic colleagues around the world have successfully “cured” a rare number of pets with megaesophagus. In cases of acquired megaesophagus in adult dogs, treating the underlying cause (such as supplying thyroid hormone to pets with hypothyroidism,) if it can be determined, is critical in preventing further damage to the esophagus.
