Cyanobacteria, which produce toxic cyanobacteria, can be found in freshwater or saltwater bodies. Warm (usually above 75 degrees) and sunny weather makes the perfect environment for them to grow.
Notably, in the summer, cyanobacteria thrive and are fatal to dogs. According to Pet WebMD, within minutes of exposure, they will damage a dog’s fangs. If these primitive algae bloom, they become more toxic. They are also harmful to humans.
