PDSA Vet Nurse, Nina Downing, said: "Blue-green algae can grow in all aquatic environments, but it's most prevalent in still or stagnant water during summer. This particular type of bacteria is highly poisonous to animals, and can sadly be fatal, or result in long-term health problems for those that survive."
They warn to be vigilant when walking your dog and avoid any water which looks bright and green at all costs.
Symptoms of poisoning include seizures, twitching or diarrhoea amongst other ailments.
