LONDON — A peer-reviewed study published in the journal Environmental Health Perspectives in February 2026 confirmed that companion animals — particularly dogs — can develop mesothelioma following exposure to asbestos fibers, adding to a growing body of evidence that pets living in asbestos-contaminated environments face serious long-term health risks.
The study, conducted by researchers at the University of Glasgow School of Veterinary Medicine and the Collegium Ramazzini in Italy, analyzed pathology records from 847 dogs diagnosed with pleural mesothelioma across Europe and North America between 2010 and 2024. Occupational asbestos exposure in the household — typically through a human family member working in construction, shipbuilding, or remediation — was identified as a significant risk factor.
Dogs are considered a sentinel species for asbestos-related disease because their shorter lifespan compresses the latency period between exposure and tumor development, potentially providing earlier warning of household contamination than human health monitoring alone.
For restoration contractors performing asbestos abatement in occupied or recently occupied structures, the findings reinforce the importance of comprehensive containment, negative air pressure, and decontamination protocols. Contractors should advise clients to relocate all pets — not just children and pregnant women — before abatement work begins and until post-clearance air sampling confirms fiber levels below the EPA action threshold.
The Asbestos Disease Awareness Organization has called for updated EPA guidance to explicitly include companion animal protection in residential asbestos abatement planning, noting that current regulations focus exclusively on human occupant protection.
