Pet owners are being warned after eight dogs have died from suspected poisoning.
The British Veterinary Association (BVA) is urging owners to take steps to keep their dogs safe when walking near freshwater bodies this summer, as the warm weather brings with it an increased risk of toxic blue-green algae growth.
Blue-green algae, or cyanobacteria, is a group of bacteria that can contain dangerous toxins which can be harmful and potentially fatal to pets, livestock and birds if ingested even in small quantities.
