A hematological research regarding gestation anemia at the bitch was conducted. In the 60 cases, pregnant females, several hematological determinations were made. The focus was on the incidence of anemia during bitch gestation, on the delimitation of relative anemia from real anemia, on the criteria allowing this delimitation and on how serious real anemia is and the criteria used. Out of the 60 cases investigated, 44 showed anemia, with the hemoglobin’s value under 12g/dl (criterion used for non-pregnant females); according to the criterion for pregnant females (the hemoglobin’s value under 11g/dl), only 25 cases are compatible with anemia, with real anemia. In our research the cases where the hemoglobin’s values were between 11-12g/dl were classified as with relative anemia. This condition is considered to be the result of hemodilution which installs during gestation. Out of the 25 cases of real anemia, 11 are characterized by slight anemia (hemoglobin between 1011g/dl), 9 by a moderate form (hemoglobin between 8-10g/dl) and only 6 may be considered with a serious form of anemia. Normocytic and normochrome anemias are predominant.
