Plain-English summary
A study looked at mammary gland tumors in 101 dogs and found that small-breed dogs had a lower chance of having malignant tumors compared to larger breeds. Specifically, only 25% of small-breed dogs had cancerous tumors, while 58.5% of other breeds did. Smaller tumors (less than 3 cm) were more common in small breeds, and those with less invasive tumors tended to live longer. This suggests that if your small dog has a mammary tumor, it might be less serious than in larger dogs.

Abstract
Clinicopathological features of mammary gland tumors (MGTs) in 101 dogs were evaluated retrospectively. The incidence of histological malignancy in 60 small- and 41 other-breed dogs were 25% and 58.5%, respectively. In 82 epithelial MGTs, small-sized tumors (< 3 cm) or non-invasive tumors were predominant in small breeds. In multivariate survival analysis, small breed (p=0.048) and lower stage of tumor cell invasion (p=0.006) were significantly associated with longer survival time. These results suggest that the incidence of histological or biological malignancy in MGTs is lower in small-breed dogs than in others.
