Abstract: Megaoesophagus is a condition characterized by dilatation and decreased motility of the oesophagus, leading to difficulty in swallowing and regurgitation of food. This study aimed to investigate prevalence, clinical features and haemato-biochemical changes associated with megaoesophagus in dogs. During the study period, 33 dogs were diagnosed with megaoesophagus through history, clinical findings, and radiography. Clinical signs included regurgitation, weight loss, skin lesions, muscle wasting, cough, respiratory distress, and eye lesions. Labrador Retrievers were the most affected breed, with males being more commonly affected than females. Haematological examination revealed significant leukocytosis, neutrophilia, and eosinophilia, with a decrease in lymphocyte and monocyte count. Serum T4 values were found to be decreased in affected animals, with 77.8 percent having serum T4 values below 2µg/dL. This study highlights the importance of early diagnosis and management of megaoesophagus in dogs to prevent potential complications.
