Routine hematology and clinical chemistry in female dogs with benign and malignant mammary tumors

Routine hematological and serum biochemical screening was done in 61 female dogs with benign mammary tumors and 51 female dogs with malignant mammary tumors. Most parameters were not significantly different from age-matched female controls; moreover, no significant difference could be observed between animals with benign and malignant tumors. It is concluded that routine hematology and biochemistry offer little diagnostic or prognostic benefit in female dogs with mammary tumors.
