Blooms of blue-green algae can produce harmful toxins which stop a dog’s liver from functioning properly, and can be fatal.

Blue Cross for Pets state types of blue-green algae can kill a dog just 15 minutes to an hour after drinking contaminated water.

If you think you have spotted blue-green algae in water and cannot see any signage, report it to the Environment Agency which can investigate.
