High levels of blue-green algae are currently triggering recreational alerts at 10 lakes in Indiana this summer, according to the Indiana Department of Natural Resources.
The algae has rarely been toxic to humans in Indiana, but even small amounts of the toxins can be dangerous for pets, said Cyndi Wagner with the Indiana Department of Natural Resources.
“Even in those small amounts, if a dog drinks enough of the water they could succumb to the effects of the toxin and the toxins — there are four different ones — some of them are neurotoxins and some of them are liver toxins,” Wagner said.
