As the weather is forecast to heat up over the weekend, owners are urged to be aware of the symptoms of blue-green algae poisoning if their dog has been swimming or paddling in open water, such as rivers and lakes.

What is blue-green algae?

Blue-green algae is a term that describes a group of bacteria called cyanobacteria, and it is found in freshwater bodies such as lakes, ponds, canals, rivers and reservoirs.

The chemicals produced from the bacteria are highly toxic to dogs and are also dangerous to other animals, including cats, horses, birds and cows, and can even be harmful to humans when ingested in small quantities.

Not all blue-green algae is poisonous, but bodies containing algal blooms should be avoided.

The algae appear as a green or greenish-brown scum on the surface of the water and dogs can swallow it by drinking water from an affected body of water, or while licking their fur after going for a swim.

Dogs can even come into contact with the bacteria even if they don’t go into the water as toxic blooms can be blown to the edges of bodies of water.

Some types of blue-green algae can have fatal effects and can kill a dog in as little as 15 minutes to an hour after drinking contaminated waters

If caught early enough, a vet will attempt to make your dog vomit to try flush the toxins out of the body. There is no antidote, but if medical intervention occurs early this gives your dog the best chance at survival.

- Keeping your dog away from bodies of water that you suspect to contain blue-green algae

- Do not allow your dog to swim or paddle in waters that contain blue-green algae

- Avoid letting your dog drink water that could contain blue-green algae. Wind often blows blue-green algae to the edges of ponds and lakes and higher concentrations of toxins can reside here, where your dog is more likely to drink.
