RSPCA Worker Endures 57.1C Heat in Locked Car to Demonstrate Pet Danger
As temperatures continue to climb across the UK, an RSPCA worker deliberately shut himself inside a sweltering vehicle for 25 minutes to show what dogs experience when left in hot cars. Chris O'Brien, from RSPCA Cymru, conducted the experiment outside the charity's Cardiff office on a warm day, equipped with a digital thermometer and stopwatch.
The challenge began with the interior temperature at 23.3C. Within just five minutes, it surged to 35.1C. By the 10-minute mark, the mercury rose to 43.6C, with O'Brien noting his heart racing and breathing becoming laboured. He said: "I am baking. It is so, so hot in here. I can't even begin to tell you." He added: "Obviously I'm sweating a lot. Dogs regulate their body temperature very differently to humans, so they would struggle even more in these conditions."
Temperature Soars Past 50C in Minutes
O'Brien highlighted that while he could exit the vehicle at any point, a dog would have no such understanding, meaning the animal would grow increasingly distressed. After 15 minutes, the temperature soared to 48.8C, surpassing 50C just two minutes later. "Everything in the car is absolutely boiling," he said. "I cannot imagine how a dog would feel." By the conclusion, the thermometer displayed a remarkable 57.1C. O'Brien added: "I cannot believe the impact this has had in such a short space of time. This is so dangerous. Never leave a dog in a hot car."
RSPCA Urges Caution Amid Heatwave Forecast
The stark warning comes as meteorologists forecast another bout of scorching weather across parts of the UK, with temperatures anticipated to climb into the 30s Celsius. The RSPCA is urging owners to remember that leaving a dog in a parked vehicle — even briefly or with windows slightly ajar — can rapidly prove fatal. The charity highlights that dogs cannot regulate their body temperature as efficiently as humans, rendering them considerably more susceptible to heatstroke.
