The digestive injuries appear depending on the causal agent, his duration and on the degree of exhibition. The spirocercosis compromises the digestive, circulatory and osseous systems, and the helicobacteriosis, is related to gastritis, gastroduodenal ulcerations and stomach neoplasics processes, reporting to H. pylori in dogs and cats, as zoonótic possibility. This study was realized in the Canine Section of FCV-UCV’s Bioterio, in 43 dogs characterized by street antecedents and varied nourishing, medical and sanitary managings. Its objectives were to register pathologies in stomach and to determine the presence of bacteria of the Helicobacter genus in gastric injuries associated with this bacterium. The diagnostic techniques showed 16.3% of nodules for S. lupi, and 13.9% of inflammatory injuries and sores gastroduodenals; 100% of positivity to ureasa. The histopathology revealed 58.14% of acute superficial gastritis, 20.93% of chronic superficial gastritis and 6.98% of chronic atrophic gastritis; the histochemist demonstrated espiral bacterias in gastric mucous, also, antibodies were detected against H. pylori to 4.7%. There was no bacterial growth in cultures of biopsy. The non paramétric test of Friedman revealed no significance between the sex relation (0.0833) and esophagus gastric injure (0.1561), but if, for the sex (0.0455) in relation with gastric injuries (0.1196). The managing of the population in study had influence in the appearance of spirocercosis, and the colonization of Helicobacter spp., in addition, they were inclined to the infection with H. pylori, being the dog then an alternative as model for the study of the helicobacteriosis
