Keywords:Dog, haematological parameters, disease
AbstractHaematological examination was carried out on 23 clinically affected dogs with various diseases or conditions at Teaching Veterinary Hospital of Chittagong Government Veterinary College for a period of 5 months from July to November 2003. On haematolo-ical examination, total erythrocyte count, haemoglobin concentration and packed cell volume were recorded to be normal in dog irrespective of types of breed except anaemia. Decreased haematological values (TEC 2.1-2.5 million / cmm, Hb 3.4-5 g% and PCV 12-13%) were recorded in anaemic cases. The elevated erythrocyte sedimentation rate was recorded in maximum cases of dog. However, higher leukocyte count (19-26.7 thousand / cmm) was recorded in dermatitis, mammary tumor, abscess and leptospirosis of dogs. On differential leucocyte count, lymphocytes and eosinophils were counted higher while neutrophils were counted lower in dermatitis of German Shepherd and local breeds. Alarming lower percentage of lymphocytes (12-13%) and higher percentage of neutrophil (70-72%) and monocyte (9-10%) were registerd in leptospirosis. On the other hand, lymphocytes count in fever (40-58%), conjunctivitis (54%) and fracture (46%) were higher while lower percentage of neutrophil was recorded as 35-54%, 36% and 52% respectively in Shamoyed breed.
