Indiana warns of danger to dogs from algae

If you are taking your dogs to play in an Indiana waterway, state agencies say to be wary of blue-green algae blooms.

The algae blooms typically happen from late spring to early fall in Indiana. They produce toxins that can be harmful to people, livestock and pets, particularly dogs according to the Indiana Department of Environmental Management and the Indiana Board of Animal Health.

Dogs are particularly susceptible to algae poisoning because the scum can attach to their coats and be swallowed during self-cleaning.

Water containing high levels of blue-green algae may appear greenish and, occasionally, with shades of blue, brown or white. Some appear to have a thick, paint-like scum on the surface.

Public health officials suggest avoiding contact with waters showing algae. You should wash off with warm, soapy water after time in reservoirs, lakes, rivers, and streams. For more information on blue-green algae, visit
