Dog Hot Car and Heat Stroke Welfare

Leaving dogs in hot cars causes rapid and fatal hyperthermia that kills thousands of dogs annually, representing a preventable welfare emergency.

Key Facts

A car's internal temperature can rise to 47 degrees Celsius within minutes on a warm day
Dogs cool primarily through panting rather than sweating, making them particularly vulnerable to heat
Brachycephalic (flat-faced) breeds are at highest risk from heat stroke due to impaired airway
Heat stroke causes organ failure, brain damage and death within minutes without intervention
In the UK, police can break into a vehicle to rescue an animal under imminent threat
Signs of heat stroke include excessive panting, drooling, collapse, vomiting and loss of consciousness

Welfare Considerations

Hot car deaths are entirely preventable tragedies that cause horrific suffering. A dog in a hot car experiences a rapid spiral from discomfort to distress to agony as body temperature rises beyond the ability to compensate. Brain damage begins at around 41 degrees Celsius. Death follows. The suffering before death is extreme and prolonged relative to the brief window in which intervention is possible. No errand justifies leaving a dog in a warm car. If you see a dog in a hot car showing distress, call 999 - the police have authority to act and time is critical.

What You Can Do

Never leave a dog in a car on a warm day, even with windows open or in shade
Call 999 immediately if you see a dog in a car showing heat stroke symptoms
Cool a heat-stroked dog with cool (not cold) water and seek emergency veterinary treatment
Share awareness of hot car dangers in your community especially before warm weather periods
Support campaigns for public education about dog heat risks including during spring and autumn
