Plain-English summary
A group of 34 female dogs with mammary tumors underwent ultrasound exams to help determine if their tumors were benign or malignant. The study found that malignant tumors had a greater depth-width ratio (D/W) compared to benign ones, which could help vets diagnose the type of tumor. While the D/W measurement was not perfect, it showed a good level of accuracy in identifying malignant tumors. This information can assist veterinarians in making better treatment decisions for dogs with mammary tumors.

Abstract
Depth-width ratio (D/W) is the only quantitative item in the criteria recommended by the Japanese Ultrasound Society for the evaluation of breast tumors in humans. However, the usefulness of the D/W has not been evaluated in dogs. Eighty-six mammary masses in 34 female dogs underwent ultrasonographic examination to determine the D/W and other characteristics. Results of ultrasonographic and histopathologic examinations were compared. The D/W of malignant tumors was significantly greater than that of benign tumors, and it had a sensitivity of 56.3% and a specificity of 92.9% for the diagnosis of malignancy when the threshold of D/W was 0.7. In addition, irregular margin, polymorphous shape and heterogeneous internal echographic characteristics were correlated with malignancy.
