An RSPCA worker locked himself inside a hot car for 25 minutes to experience exactly what happens to a trapped dog. 🌡️
Chris O'Brien shut himself in the vehicle outside the office on a warm day to film how fast conditions turn deadly.
Armed with a digital thermometer and a stopwatch, he recorded the physical toll the rising heat took on his body.
The experiment started with the air inside the car at a comfortable 23.3C.
Yet within just five minutes, the internal temperature rocketed to 35.1C.
By the ten-minute mark, the thermometer climbed to 43.6C, causing his heart to beat faster and his breathing to become heavy.
"I am baking. It is so, so hot in here. I can't even begin to tell you," he said during the recording.
Dogs regulate their body temperature very differently to humans and struggle significantly more under such extreme conditions.
After 15 minutes, the heat reached 48.8C, before crossing the 50C threshold just two minutes later.
By the end of the 25-minute challenge, the final temperature inside the vehicle reached a staggering 57.1C.
Forecasters are currently predicting another spell of hot weather across parts of the UK, with temperatures expected to climb into the 30Cs.
