A cooling splash in a pond or lake can be very tempting during the summer, for both you and your dog. However, it’s important to stay alert to potential risks, particularly blue-green algae.
Blue-green algae (also known as cyanobacteria) can be extremely toxic to dogs. Even small amounts can cause serious illness, including seizures, and in some cases can be fatal.
What does blue-green algae look like?
It doesn’t always look like “algae” in the traditional sense, so it can be easy to miss. Watch out for:
- Green, blue-green, or turquoise scum on the water’s surface
- Paint-like streaks or swirls in the water
- Clumps that resemble pea soup or floating mats
- A musty, earthy, or slightly sweet smell
- Discoloured water, especially near the edges of ponds or lakes
If you see warning signs posted always take them seriously and keep your dog well away from the water.
Not sure if it’s blue-green algae?
You can use the free Bloomin’ Algae app to help. The app lets you upload photos of suspicious water, which are then reviewed by experts to identify whether blue-green algae is present.

Why is it so dangerous?
Exposure doesn’t just happen from drinking contaminated water. Dogs can also be affected by:
- Swimming or paddling in affected areas
- Accidentally swallowing water while playing
- Licking algae or contaminated water off their fur or paws afterwards
What to do if your dog is exposed
If you suspect your dog has come into contact with blue-green algae:
- Rinse them thoroughly with clean water as soon as possible
- Prevent them from licking their coat
- Contact your vet immediately for advice
Blue-green algae can act very quickly, so early action is critical.
