Scots have been warned after toxic algae which is poisonous to dogs was discovered at a popular beauty spot.
Loch Lomond & The Trossachs National Park shared worrying pictures of the blue-green algae on Sunday.
They warned the potentially fatal algae had been seen around Drumkinnon Bay and Duck Bay on Loch Lomond.
An official warning from the park on Facebook read: "Blue-green algae can produce toxins that can kill dogs and other animals.
"In humans it can cause rashes after skin contact and illnesses if swallowed. Where there is blue green algae our advice is for people to keep themselves and their pets out of the water."
Photos of the algae - which is typically a problem in warmer months - showed where it had bloomed on the Loch's shore, causing the water to turn green in colour.
It can also produce "earthy or grassy odours" and can also cause foaming on the shoreline.
The algae can produce toxins that are harmful to humans and potentially fatal to dogs.
Owners are warned their pets should be kept out of the water where an algae bloom has appeared.
According to the Scottish SPCA, the symptoms from ingesting the toxins can appear within a few minutes or hours, and commonly include vomiting, diarrhoea, disorientation, breathing difficulties and seizures.
