Abstract   

This project was designed to study the haematological values and the serum electrolytes (sodium, potassium and chloride) levels in the dogs exhibiting diarrhoeal sings. One hundred dogs showing diarrhoal sings were selected from Dog Hospital, College of Veterinary Sciences, Lahore, while ten healthy dogs were also used as control group. Tentative diagnosis of cause of diarrhoea was tried to establish in each animal of experimental group. Blood samples were collected from all the animals of both groups. The values of haematological parameters (TEC, PCV, ESR and Hb) and serum electrolytes (sodium, potassium and chloride) were determined on all blood samples. The changes in blood values of each case were correlated with its tentative diagnosis. The conditions observed were parvo virus infection, parasitic infestation, mixed infection, canine distemper and dietary distrubance. These conditions of experimental dogs were named as groups A, B, C, D and E, respectively and group F acted as control. Haematological values (TEC and PCV) of groups A, B, C, D and E were significantly different (P < 0.001) from means of control group. The mean values of erythrocyte sedimentation rate of groups A, B, C, D and E were not significantly different from each other but were significantly different (P < 0.001) from means of groups D and E. The mean values of serum sodium of groups A, C and D were not significantly different from each other but were significantly different (P < 0.001) from the mean values of groups B, E and F. There was non-significant difference among the mean values of serum potassium level of groups A, B, C, E and F. All the dogs of experimental groups exhibited macrocytic nOrrnochromic anaemia.
