If you’re a regular visitor to local parks and lakes, you may have seen the notices around the lake warning that blue-green algae has recently been detected. While the water might look tempting on a sunny day, it’s important to know that this algae is extremely harmful – both to humans and to our beloved animal companions.
At Jarden Vets, we want to make sure everyone in the local community understands the risks, so you can keep your companions safe while enjoying the great outdoors.
What is Blue-Green Algae?
Despite its name, blue-green algae isn’t actually algae at all. It’s a type of bacteria called cyanobacteria that thrive in nutrient-rich still, warm water and forms visible clumped masses on the surface of lakes and rivers.
You might notice:
- Green, blue, or brown scum on the water surface
- Paint-like streaks across the lake
- A foul, musty smell
Even if you can’t see much on the surface, blue-green algae can still be present in the water. This is why authorities issue warnings whenever it’s detected.
Why is it Dangerous?
The toxins released by blue-green algae can cause serious illness or even be fatal if ingested. The risks are especially high for dogs and other animal companions because they are more likely to drink from or swim in the water.
In animal companions, symptoms can include:
- Vomiting and diarrhoea
- Drooling
- Weakness or collapsing
- Seizures
- Breathing difficulties
Even small amounts of contaminated water can be deadly for dogs. Sadly, cases of dogs passing away after exposure to blue-green algae are reported every summer across the UK.
For humans, it can cause:
- Skin rashes and irritation
- Stomach cramps, nausea, and vomiting if swallowed
- Eye irritation from contact with the water
How to Keep Your Animal Companion Safe at Local Parks and Lakes
- Avoid the lake completely. Don’t let your dog paddle, swim, or drink the water.
- Bring fresh water. Carry a bowl and plenty of drinking water for your animal companion.
- Keep to the paths. Many dogs love running straight into lakes, so keeping them on the lead near water is safest.
- Be cautious with toys. Avoid throwing balls or sticks into the lake.
- Check local notices. Follow safety signs around the park and keep updated with park announcements.
What To Do If Your Dog Has Been in Contact with Blue-Green Algae
- Call your vet immediately as blue-green algae poisoning can progress very quickly, so don’t wait for symptoms to appear.
- Rinse your companion with clean water as soon as possible to wash algae off their coat.
- Do not let them lick their fur as this can increase the amount of toxin ingested.
At Jarden Vets, we urge you to seek emergency help if you suspect your dog has been exposed. Acting fast can save lives.
Enjoying Local Parks & Lakes Safely
Our local country park is a wonderful place for walks with your animal companion, but during this period it’s best to stick to dry paths, grassy areas, and shady spots for playtime. With a bit of extra care, you can still make the most of the park while keeping your companion safe and healthy.
Blue-green algae might not look dangerous, but it’s one of the most serious hazards for dogs in summer. Please take care around the local parks and lakes and spread the word to other dog owners you meet. By staying alert, you can protect your animal companion, and still enjoy your summer adventures together.
