ABSTRACT. Digestive diseases continue to be the reason for frequent visits in veterinary clinics and inflammatory pathologies are the most frequent cause. The goal was to evaluate the macroscopic and microscopic changes of the gastric and duodenal mucosa through of flexible endoscopy and biopsies based on criteria proposed by Jergens et al (2014) and Slovak et al (2015), in dogs that consulted in the hospital "Prof. Dr. José Vicente Núñez", San Lorenzo - Paraguay. Five animals older than one year of age, without distinction of race, size and sex were evaluated; all animals suitable to undergo deep anesthesia, endoscopy and gastroduodenal biopsy. Clinically two patients reported mild vomiting and one of them associated with weight loss. Endoscopy performed showed granularity; hyperemia; lymphatic dilation and mass. Biopsies displayed dilatation of lymphatic vessels in the mucosa; intraepithelial lymphocytes; inflammatory infiltrate in lamina propria; fibrosis in lamina propria and atrophy of the villi. Interpretation of the results according to the standards used was irrelevant in all cases. However, two cases presented symptoms and macro- and microscopic alterations coinciding with gastropathy and one of the cases associated with mild atrophic duodenitis, when to compared with asymptomatic animals.
