Can Dogs Develop Mesothelioma?

There has been several reported cases of canine mesothelioma. Malignant mesotheliomas found in dogs are similiar to human mesotheliomas, although less asbestos fibres are found in lung tissue of dogs compared to humans, and the average age for diagnosis is around 8 years.



Family pets are thought to have been exposed to asbestos fibres in their owners homes, i.e. where friable (old, crumbling) asbestos flooring, insulation or textiles exist. Family pets can also pick up asbestos fibres thier owners work clothing on a daily basis, or from land where housing has been demolished and asbestos remnants remain.


Clinical studies from postmortems of six dogs found that two died from pleural mesothelioma (involving the lung), one pericardal ( membrane surrounding the heart), one peritoneal (involving the abdomen), and two with mesothelioma of involving both pleural and peritoneum.


Mesothelioma in dogs has the same progressive clinical outcome – with a grave prognosis as mesothelioma found in humans, although mesothelioma in some dogs has been cured as they tend to have a stronger immune system than humans
