Is tanalised timber harmfull to pets?

Tanalised timber, treated with preservatives to resist rot and insects, can be harmful to pets due to the chemicals used in the treatment process, such as copper, chromium, and arsenic in older formulations. While modern treatments have reduced toxicity, ingestion of wood or exposure to treated surfaces can still pose risks. It's best to ensure pets do not chew on or ingest tanalised timber and to consult a veterinarian if you have concerns about exposure. Always monitor pets around treated wood products.
