Police are reminding dog owners not to leave their pets in vehicles in the warm weather.
Yesterday officers were called to reports of a dog which had been left in a van in Douglas.
They say the officer who attended determined the dog was not distressed and was asleep.
In a post on Facebook the Isle of Man Constabulary said: "Based on the condition of the dog it was thought that smashing the window would cause more distress than waiting for a period of time for the owner to return."
The police officer is said to have given the owner ‘suitable advice’ on their return.
The spokesperson added: "Although this was a good conclusion please don’t leave dogs in vehicles unless they are adequately cooled and ventilated.
"If we have to break a window to keep a dog safe we will do."
