Gastroenteritis cases are commonly encountered in small animal practice. This study aimed to estimate oxidant-antioxidant status in gastroenteritis affected dogs. This study was applied on seventeen (17) dogs, 10 of them had sign of gastroenteritis and the reminders (7) were apparently healthy dogs enrolled as a control. The they undergo thorough physical, clinical
examination and blood samples were withdrawn from each animal for estimation of hematologic alterations, SOD, GPx, Catalase,TAC,MDA, H2O2, cortisol, Zn,Cu, Cl, K and Fe levels. Reduction in hemoglobin, PCV, catalase and GPx along with significant elevation in SOD and cortisol were recorded. Gastroenteritis has an impact on oxidant-antioxidant
equilibrium in dogs
