Abstract. Haematological studies were conducted in 19 dogs (8 from small and 8 from medium-size breeds, 15 of which over 8 years of age) with mammary gland carcinoma at different stages of development. Blood samples were collected after a single venipucture of v. cephalica antebrachii in tubes with EDTA as anticoagulant. Complete blood count parameters: haemoglobin (g/L), haematocrit (%), erythrocytes (T/L), mean corpuscular volume (MCV, fL), mean corpuscular haemoglobin (MCH, pg), mean corpuscular haemoglobin concentration (MCHC, g/L), red cell distribution width (RDW, %), leukocytes (G/L), thrombocytes (G/L) were determined. Differential white blood cell counts were evaluated on blood smears stained with Hemacolor. The results showed anemia with erythropenia, without significant changes in erythrocyte indices, thrombocytopenia and leukocytosis, and slight variations in differential white blood cell count.
