r dog away from lakes and ponds that you know, or suspect may, contain blue-green algae.
Dogs should not be allowed to swim or paddle in water that contains blue-green algae.
Don’t let dogs drink from water that may have blue-green algae in. Because the wind often blows blooms of algae to the edges of ponds or lakes, higher concentrations of the toxin are more likely to be present in the parts of the water your dog may drink from.
Take note of signs warning of the algae during dog walks and follow the information given.
What to do if you spot blue-green algae
*If you think you have spotted blue-green algae in water and cannot see any signage, report it to Natural Resources Wales on their incident hotline: 0800 80 70 60 (24 hours).
A spokesman for NRW said: "We ask people and authorities to report algal blooms, including blue green algae, to us via our incidents hotline.
"Our responsibility is to investigate and take samples to test for any algal presence.
"If our tests confirm blue green algae, we can advise on how to manage the problem and advise the land owner or local authority to erect warning signs and notify the appropriate people.
"We would do the same for any waterbody we’re responsible for."
