To which organ is osteosarcoma most commonly known to metastasize in dogs?

Osteosarcoma in dogs is primarily known for its propensity to metastasize to the lungs. This aggressive bone tumor often spreads through the bloodstream, and the lungs are a common site for secondary tumor development. Once osteosarcoma is diagnosed, the likelihood of pulmonary metastasis is significant, which is a critical aspect to consider in treatment planning and prognosis.

While osteosarcoma can potentially spread to other organs, the lungs are typically the first location where metastatic disease manifests. Early detection of lung metastasis can influence the management strategy and outcomes for dogs diagnosed with osteosarcoma. Understanding this tendency is essential for veterinary oncologists as they assess the disease progression and develop appropriate treatment regimens.
