Visceral leishmaniasis (VL) is a common disease that affects multiple systems and has a chronic evolution time. Among the laboratory characteristics that may occur, bone marrow changes may range from hypoplasia to both erythroid and granulocytic hyperplasia. Therefore, the present study aims to perform a clinical and laboratory analysis of the findings in a dog with erythroid hypoplasia and granulocytic hyperplasia associated with VL. A 7 - years-old male Irish Setter dog was attended at the Ivon Macêdo Tabosa Veterinary Hospital of the Federal University of Campina Grande (HVIMT / UFCG) presenting epistaxy, weight loss and hyporexia. Complete blood count, serum biochemistry analysis, urinalysis, amd a myelogram with hemoparasites were requested. The complete blood count showed normochromic normocytic anemia and a decrease in the number of platelets with platelet aggregates. Serum biochemistry revealed hypoalbuminemia and hyperproteinemia. Urinalysis showed no clinically relevant changes. Leishmaniasis amastigotes were observed in the myelogram along with erythroid hypoplasia and granulocytic hyperplasia. The animal was treated with the combination of milteforan, allopurinol and domperidone, however the tutor did not return for the patient's reassessment. In the light of the above, a clinical laboratory approach of a patient with VL is important for a better treatment and to improve the prognosis. Further studies should be performed to better understand the hematopathological responses to this disease.
