Background: Upper gastrointestinal tract (GIT) disorders in dogs are a significant concern in veterinary medicine, as they can lead to various clinical manifestations ranging from mild discomfort to severe systemic illness. The upper GIT encompasses the oesophagus, stomach and duodenum, with disorders affecting these organs potentially resulting in symptoms such as vomiting, inappetite and dehydration. Given the wide range of possible conditions that can affect the upper GIT in dogs, early and accurate diagnosis is essential to initiate appropriate treatment and management strategies. The present study investigated the affections of GIT in dogs.&nbsp; 
 
Methods: During the study period, from May to October 2024, 2042 dogs were screened, presented at VCC, College of Veterinary Science and Animal Husbandry, Jabalpur (M.P.). Among them, 132 dogs were suspected of having GIT affections, out of which 30 dogs were selected for radiographic, abdominal sonography and endoscopic examination in which 28 dogs were confirmed to have upper GIT affections.&nbsp; 
 
Result: The overall occurrence of upper GIT affections in dogs was recorded as 01.37% and among the suspected dogs, it was 21.21%. The most consistent clinical signs observed were chronic vomiting (100%), followed by inappetite (92.86%), dehydration (89.29%), retching (57.14%), haematemesis (32.14%), weight loss (28.57%), ptyalism (21.43%) and dysphagia (10.71%). The ultrasonographic, radiographic and endoscopic examination revealed higher occurrence of chronic gastritis 50.00% (14/28) followed by gastric ulcers and erosions 35.71% (10/28), gastric foreign body 10.71% (3/28), oesophagitis 07.14% (2/28), megaoesophagus 03.57% (1/28) and sialocele 03.57% (1/28).
