Dog owners are being warned about the dangers of a highly poisonous algae that bloomed during the heatwave.
The scorching weather last week meant that blue-green algae had bloomed in the county, creating a potential hazard for pets.
The Grove Veterinary and Hospital Group is now urging pet owners to be aware of the algae if their pets swim in ponds and lakes.
Blue-green algae, despite its name, is not algae but a group of bacteria known as cyanobacteria and some types of bacteria contain toxins that are highly poisonous and can be fatal to pets.
These bacteria form clumps resembling algae and are most common in non-flowing fresh water such as ponds, lakes, and rivers.
A spokesman for The Grove Veterinary group said: "Dogs are particularly at risk from the algae if they swim in affected water and ingest it.
"The toxins in the algae stop the liver from functioning and can cause long-term health issues.
"If you think that your dog may have been exposed to blue-green algae, contact your vet straight away."
