Cyanobacteria pose lethal risks to dogs in summer waters

Cyanobacteria, commonly known as blue-green algae, pose a significant health risk to dogs during warm summer months. These microscopic organisms thrive in standing or slow-moving water under conditions of high temperatures, intense sunlight, and high nutrient levels from agriculture or sewage plants.

When algae blooms occur, the water can visibly change color and release toxic substances called cyanotoxins. Dogs are particularly vulnerable because they do not just swim in the water, but also drink from it, lick their wet fur, or sniff the shoreline, leading to rapid ingestion of high doses.

One common toxin, microcystin, specifically targets the liver and can cause rapid liver destruction or complete liver failure.
