The aim of this study is to investigate the diabetes in obese and emaciated dogs. Overweight dogs are considered clinically obese when body weight exceeds optimum weight for body size by at least 15%, while dogs are considered emaciated when they lose a substantial amount of both body fat and muscle tissue, resulting in a body weight that is at least 20{u2013}25% less than an ideal weight.Therefore, the present study was designed to classify 125 dogs according to their body condition scores (BCS); age and health state into four main groups (apparently healthy, diseased, young and old); respectively and investigate some of their biochemical and hematological blood constituents. The first group of apparently healthy dogs, old obese dogs showed significant (p<0.05) increase in alkaline phosphatase enzyme (ALP). Random blood sugar (RBS) level showed significant (p<0.05) decrease in young emaciated dogs. Also, there was significant (p<0.05) increase in the values of erythrocytes count (RBCs), hemoglobin concentration (Hb) and Packed cell volume (PCV) of old obese dogs. Whilein the second group of diseased dogs, old emaciated dogs showed a significant (p<0.05) increase in ALP. RBS showed significant (p<0.05) increase in young obese dogs. Also, young obese dogs showed a significant (p<0.05) decrease in Urea.It was concluded that age and BCS have significant effect on different blood parameters and health state of the dog. Also, there are no diabetic cases in our study
