Overview

• Heatwave followed by heavy rain has triggered toxic blue-green algae blooms in lakes and ponds across UK hotspots such as Llandrindod Lake, Loch Watten, Cumbria and Lancashire.
• Cyanobacteria blooms release potent toxins that can cause vomiting, diarrhoea, seizures and acute liver or neurological damage in dogs within minutes to hours of exposure.
• The British Veterinary Association warns there is no known antidote for blue-green algae poisoning and stresses that immediate veterinary care is vital to improve a dog’s chance of recovery.
• Pet experts recommend avoiding stagnant or discoloured water, rinsing dogs’ coats after swims, keeping pets on leads near waterways and watching for signs of illness such as drooling or disorientation.
• Local councils and environmental agencies are posting on-site warnings and online resources like Bloomin’ Algae offer real-time reports to help owners plan safe outings.
