The present study was carried out to study the ultrasonographical characteristics of malignant canine mammary tumors. In ultrasonographic studies performed on 36 animals with malignant mammary tumors, 26 cases (72.22%) showed indistinct margins whereas in remaining ten cases (27.78%), the margins were circumscribed. All tumors showed heterogenous parenchymal echotexture, in which ten cases showed cystic spaces (anechoic areas) in parenchyma and remaining cases showed mixed echogenecity throughout parenchyma A hyperechogenic line delimiting the neoplastic tissue from the healthy tissue was observed around the tumor in 26 cases.
