The hematologic values were examined from 74 healthy mixed breed dogs in the area of Seoul. The results obtained are summarized as follows; 1. Mean${\pm}$SD values and ranges of red blood cell(RBC) count were $6.16{\pm}0.92{\times}10^6/{\mu}l$ and $4.40{\sim}8.62{\times}10^6/{\mu}l$, of hemoglobin(Hb) content $14.90{\pm}2.42g/100ml$ and 8.7~19.2g/100ml, of packed cell volume(PCV) $45.47{\pm}6.16ml/100ml$ and 30~57ml/100ml, of mean corpuscular volume (MCV) $74.80{\pm}6.83fl$ and 54.08~90.90fl, of mean corpuscular hemoglobin (MCH) $24.41{\pm}3.91pg$ and 14.19~32.97pg, of mean corpuscular hemoglobin concentration (MCHC) $32.07{\pm}3.24g/100ml$ and 22.23~39.76g/100ml, respectively. 2. The RBC count value in the age group of 3~4 years was higher (p<0.05) than the total RBC count value. The Hb content value in the age group of less than 6 months was lower (p<0.01) but in the age group of 1~2 years and the age group of 3~4 years were higher (p<0.05, p<0.01) than the total Hb content value. The PCV value in the age group of less than 6 months was lower (p<0.05) than the total PCV value. The MCHC values in the age group of 1~2 years and the age group of 3~4 years were higher (p<0.01, p<0.05) than the total MCHC value. 3. Mean${\pm}$SD values and ranges of white blood cell (WBC) count were $11.26{\pm}3.05{\times}10^3/{\mu}l$ and $6.30{\sim}18.4{\times}10^3/{\mu}l$, of band neutrophil $2.97{\pm}1.44%$ and 1~10%, of segmented neutrophil $62.81{\pm}4.92%$ and 42~70, of lymphocyte $30.55{\pm}5.69%$ and 17~50%, of monocyte $2.49{\pm}0.84%$ and 1~5%, of eosinophil $1.81{\pm}1.175$ and 1~8%, respectively. 4. The WBC count value in the age group of 7~12 months was lower (p<0.05) but in the age group of 3~4 years was higher (p<0.05) than the total WBC count value. The band neutrophil values in the age group of 1~2 years and the age group of 3~4 years were higher (p<0.05, p<0.01) than the total band neutrophil value.
