Complete blood cell (CBC) changes are directly or indirectly related to cancer and have not been reported in bitches with mammary tumors. The aim of this study was to evaluate CBC changes in 161 bitches with mammary tumors, and to correlate them with disease progression. Normocytic and normochromic anemia and neutrophilic leukocytosis were observed and correlated with disease stages III, IV and V. In conclusion, anemia and leukocytosis may be correlated with advanced stages of mammary tumors in bitches.
