Plain-English summary
A group of 110 dogs with various types of cancer had their bones examined after they passed away, and 21 of them were found to have tumors that had spread to their bones. Most of these cases involved female dogs, particularly those with mammary tumors (breast cancer), but other types of cancers were also involved. The vertebrae and the humerus (the upper arm bone) were the most commonly affected areas. This study highlights that bone metastases are quite common in dogs with certain cancers, indicating the need for careful monitoring and potential treatment options for affected pets.

Abstract
The skeletons of 110 dogs with malignant tumours of different origins were examined by necropsy examination over a 3-year period to identify bone metastases. Twenty-one cases of metastatic or multicentric tumours with bone involvement were recorded. In general, more female dogs presented with bony metastases; however, when the dogs with mammary tumours were omitted, the gender distribution of the cases was approximately equivalent. The mammary gland was the primary site of most of the metastatic bone lesions, followed by the musculoskeletal system and the respiratory system. The majority (77%) of metastases were grossly visible and present in multiple bones. However, in 23% of the cases, the metastases could be diagnosed only at the microscopical level. The vertebrae and the humerus were the most frequently affected bones regardless of the primary site and the histogenesis of the tumours. The results of this study revealed a high prevalence of bone metastases and/or bone involvement in dogs with multicentric tumours.
