Napier dog owners are being warned not to let their dogs in the water at a Napier park, after cyanobacteria was found in the pond.
The Napier City Council confirmed a blue-green substance found in the Anderson Park waterways was cyanobacteria, and have warned dog owners to keep their animals out of the water.
A council spokesperson said the area of most concern is in the pond near the model railway and lighthouse, and the creek near the Anderson Park Playground.
A vacuum truck has been used to get rid of the worst of the outbreak, and warning signs have been put up.
If your dog has come into contact with water at Anderson Park and is vomiting, has diarrhoea, has seizures, is weak or collapses, is disorientated, confused, is drooling or is struggling to breathe, to contact a vet immediately.
