Dogs die in hot cars every year in the UK despite widespread public awareness campaigns. Understanding the physiology of heat stroke and the law around rescue can save lives.
Death in a hot car is a particularly preventable and particularly distressing form of animal suffering. Dogs in extreme heat experience distress, organ failure and death within minutes. The physiological mechanism - inability to cool effectively through sweating, rapid temperature escalation - means that the window between discomfort and life-threatening emergency is extremely short. Despite decades of public education, dogs continue to die in parked cars every summer. The message needs to reach not just dog owners who deliberately leave dogs but those who underestimate how quickly temperatures rise with windows slightly open or in shade. 'Not long' is never a safe answer when temperatures are above 20C.
