Two dogs unfortunately died earlier this year in Northern Ireland from suspected contact with Blue-Green Algae. Learn what it is, where it's found, the harm it can cause, and how to act quickly to protect your dog. 

What is Blue-Green Algae?

Blue-green algae are toxic bacteria that form blooms, often appearing as green scum or mats on the water's surface. These blooms can release harmful toxins that are extremely dangerous to dogs if ingested or even if they swim in contaminated water.

Where and When Does It Appear?

Blue-green algae thrive in still, nutrient-rich waters such as ponds, lakes, rivers, and reservoirs, especially during warm weather. It can appear quickly and unpredictably, posing a threat in areas where dogs might swim or drink.

How Do Toxins Affect Dogs?

Blue-green algae toxins target the liver and nervous system in dogs, causing liver failure, neurotoxicity, respiratory distress, and gastrointestinal issues. In severe cases, these effects can quickly lead to death without prompt treatment.

What Are the Signs of Poisoning?

Symptoms of poisoning include sudden vomiting, diarrhoea, weakness, drooling, difficulty breathing, seizures, and collapse. These symptoms can develop rapidly, and it’s vital to seek immediate veterinary care to increase the chances of survival.

What Should You Do If Exposed?

If you suspect your dog has come into contact with blue-green algae, act quickly. Rinse them thoroughly with fresh water, prevent them from licking their fur, and contact a vet immediately. Rapid response is crucial to prevent serious illness or death.
