Megaesophagus is a disease caused by hypomotility and partial or total esophageal dilation, which can be congenital or acquired and subdivided into primary, secondary, or idiopathic. In the hereditary form, the pathogenesis is not fully understood, but the symptoms begin after weaning and the offspring of the litter presents underdevelopment. The main clinical sign of this disease is regurgitation after ingestion of food and water. The definitive diagnosis is based on the history, clinical examination and complementary imaging tests. The treatment is conservative, being necessary to change the alimentary management and to treat the complications that can be caused. In addition, the most affected dogs are medium to large. Therefore, the aim of this study is to report a case of congenital megaesophagus in a puppy of the Pinscher breed, with a history of regurgitation since weaning, voracious appetite and developmental delay. After the diagnosis through plain and contrasted X-rays, dietary management was initiated and the patient showed clinical improvement.
