Blue-green algae: What dog owners need to know

Blue-green algae (cyanobacteria) are not actually algae, but bacteria found in stagnant water such as lakes, ponds and slow-flowing rivers that have been exposed to direct sunlight for a long time. They often form streak-like accumulations on the surface like a carpet with a green, blue, brown or red color.

Danger for dogs (and also for people)

Blue-green algae can be life-threatening for dogs because some species produce toxic algal toxins. These toxins can damage various organs, especially the liver, kidneys and nervous system.

Precautionary measures

• Do not let your dog swim in water containing blue-green algae.
• Avoid swimming in places where there are many water birds.
• Look for warning signs such as streaks on the water surface or an unpleasant smell.
• Prevent your dog from drinking water from unknown bodies of water.

Symptoms

The symptoms appear quickly, within a few minutes to a few hours after the blue-green algae poisoning. The first symptoms are often the following:

• Diarrhea and vomiting
• Cramps and shortness of breath
• Excessive salivation and tear production
• Muscle tremors, muscle rigidity, paralysis, seizures
• Panting
• Skin redness and inflammation
• Weakness and disorientation
• Pale or bluish mucous membranes

First aid if blue-green algae poisoning is suspected:

• Remove your dog from the water immediately.
• Rinse his mouth with water.
• Take him to the vet as soon as possible.
