Dog owners in Napier are being warned to keep their pets away from waterways in Anderson Park due to the possible contamination with cyanobacteria, which can be potentially fatal to dogs.
Testings of the blue-green toxic algae in a pond and creek is underway and Napier City Council is urging dog owners to contact their vet if their pet is showing any symptoms of poisoning after drinking or paddling in the water.
Warning signs have been erected and a vacuum truck is on site to try to clear the worst of it.
People are also being urged to avoid contact with the water as a precaution.
