Here at Pawsome Vets, we want to keep your pets safe no matter the season. As we finish summer and enter into Autumn, blue-green algae can be at its worst risk to our pets’ health. So, let’s delve more into the risks of algae and look at what it is, along with how to keep your dogs safe. 

What is blue-green algae? 

Even though it is called algae, blue-green algae is not actually a true type of algae. Instead, it is a type of bacteria known as cyanobacteria. The bacteria lives in water and naturally grows in lakes, ponds and rivers.  

In small numbers, blue-green algae can be harmless, but in the right conditions, blue-green algae can bloom and multiply rapidly, causing scum that sits on the surface of the water. 

What does it look like? 

The water often appears to be blue or green in colour, hence the name, along with a green scum or foam across the surface of the water. Other colours include brown, red and even black water and scum.  

The most likely place for blooms to occur is around the edges of bodies of water, and unfortunately this is where dogs often stop for a drink or nip for a quick swim!  

What are the symptoms of blue-green algae exposure? 

Once your dog has been exposed to blue-green algae, they can start to develop symptoms within minutes or a few hours. They are more likely to develop symptoms if they have drunk or swam in the contaminated water. 

Common symptoms include: 

  • Foaming at the mouth 
  • Weakness 
  • Breathing difficulties 
  • Confusion 
  • Diarrhoea 
  • Vomiting 

In extreme cases, symptoms can develop into: 

  • Tremors 
  • Seizures 
  • Liver failure 
  • Unconsciousness  
  • Death 

Your dog may experience minor symptoms after they have been swimming, even if the water does not contain blue-green algae. However, if your dog shows any of these symptoms, it is important to contact us as soon as possible on 01623 203529. 

What to do if you suspect blue-green algae 

If you suspect that your dog has swam in or ingested blue-green algae, it is important to act as quickly as possible. This is a medical emergency and we need to see them as soon as possible!  

Although it is important to get to us quickly, there are a couple of things that you can do to help before attending the practice if you are able to. 

  • Rinse your dog: Using a hose, shower or fresh water, rinse your dog as thoroughly as possible. 
  • Stop your dog from grooming: It’s easier said than done, but preventing your dog from licking their coat is key. The use of a buster collar can stop them from ingesting algae from their fur. 
  • Wear gloves: Some blue-green algae can irritate our skin too. Wearing gloves can help to prevent irritation, as well as reducing the risk of re-introducing algae to the fur. 

What are the treatment options? 

There is no definite ‘antidote’ for treating blue-green algae, but we will treat the symptoms as they occur. In some mild exposure cases, it may just be a case of monitoring your dog to ensure that they do not start to develop symptoms. 

Other treatments can include: 

  • Anti-sickness medication 
  • Intravenous fluids to support organ function and hydration levels 
  • Oxygen therapy 
  • Activated charcoal to absorb toxins 

In some cases, your dog may need to be hospitalised for a few days for on-going care. If this was the case, we would discuss the plan with you in more detail. 

How to keep your dog safe from blue-green algae 

As with anything, prevention is key. With blue-green algae being so dangerous, it is better to avoid exposure altogether. 

Here’s some tips to prevent your dog coming into contact with dangerous algae: 

  • Keep your dog on a short lead near water that is suspicious in colour or appearance. 
  • Avoid bodies of water that have minimal current and remain still or stagnant.  
  • Keep dogs away from water that smells bad. 
  • Check for warning signs around lakes, ponds and slow moving rivers. 

If your dog loves swimming, then it’s good to get into the habit of bathing your dog after every swim. Always rinse them with fresh water and use shampoos to keep them squeaky clean. 

Keeping your dog safe from blue-green algae 

Blue-green algae can put your dog at a serious risk, so it’s super important that you are aware of water safety when out on a walk with your four-legged friend!
