Background: Haemorrhagic gastroenteritis is a highly contagious disease, which is often fatal. Causative agents of the disease are viruses, bacteria, endo-parasites and even food allergy as well as irritant drugs. Out of these, Canine Parvo Virus has emerged as a major cause of gastroenteritis in dogs. Clinical signs of the disease include fever, vomiting and severe bloody and foetiddiarrhoea with marked dehydration. Aim:Present study was conducted to evaluate alterations in the Hb concentration, TEC, PCV andErythrocytic Indices in twenty six dogs. Methodology: The study was conducted by taking 26 canines male and female out of which thirteen were infected with gastroenteritis and the rest were taken as control groups. The haematological parameters were screened by standardized procedure to stratify the difference between two groups. Results and Conclusion: The haematological analysis of diseased dogs revealed low values of haemoglobin, total erythrocyte count and packed cell volume. However, no significant difference was noticed in mean values of MCV, MCH and MCHC. Hence, there is no doubt that the findings of the present study would encourage the people to pay attention towards the general health of their pets
