Blue-green algae, or cyanobacteria, thrive in warm, stagnant water and can pose serious health risks to dogs.
They may look like a glowing, greenish film on the water’s surface and are often hard to spot. Some produce toxins that cause rapid liver failure or neurotoxicity, leading to severe, often fatal, outcomes. Always ensure your dog swims and drinks only from clean, moving water sources. Stay vigilant—your pet’s safety depends on it. 🌊🐶
