Clinico-pathological Studies on Canine Mammary Tumors in Dachshund Dog

Background: The study was aimed to find out the epidemiological data of canine mammary tumor in Dachshund breed in relation to age, growth rate, lymph node status, histological type of tumor and to compare hematological alterations of any within the tumor to compare hematological alterations due to different types of tumor. Methods: Mammary neoplasms were clinically evaluated. The measurement of total erythrocyte count (TEC), total leukocyte count (TLC), platelet count and packed cell volume (PCV %) was carried out as per standard methods. Histological observation was performed by staining with Hematoxylin and Eosin stain. Benign and malignant mammary tumors were found highest in the younger age group of 8 to 12 years and lowest thereafter. Result: 79.16% cases of the mammary tumors located in the inguinal region were found. The fast growth rate was observed in 45.83% of tumors. The hematological profile showed no difference. However, the platelet count in the malignant mammary gland tumor dogs showed significant (P<0.01) decrease than the normal and benign tumor dogs. Distant metastasis to lung was found only in 8.33% of the total mammary tumor dogs. Mammary tumors with stage I, stage II and stage III were restricted to benign mammary tumors whereas, those with stage IV and stage V were of malignant mammary tumors.
