Summary. Babesia canis infection is a significant tick-borne hemoprotozoan disease in dogs, often causing hemolytic anemia and alterations in hematological parameters. This study aimed to evaluate the effect of combined therapy with imidocarb and prednisolone on hematological indices in naturally infected dogs. Thirteen dogs showing initial clinical signs of B. canis infection were included in the study. Infection was confirmed via microscopic examination of blood smears. Hematological parameters, including erythrocyte count, hemoglobin concentration, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), leukocyte and platelet counts, and total protein, were measured before and after therapy. Treatment consisted of a single simultaneous administration of imidocarb (7 mg/kg) and prednisolone (2.2 mg/kg) within the first 24 hours after diagnosis. Following therapy, significant improvements were observed in red blood cell count, hemoglobin concentration, hematocrit, platelet count, and leukocyte distribution, indicating partial restoration of erythrocyte mass and enhancement of inflammatory and regenerative responses. MCHC, RDW, and total protein showed minimal changes, but overall trends suggest effective alleviation of hemolytic anemia and stabilization of hematological status. The findings support the use of combined imidocarb and prednisolone therapy as an effective early intervention for dogs naturally infected with B. canis
