Many people still believe it’s safe to leave their dog in the car for a few minutes – especially if the windows are open or the car is parked in the shade. But even on a mild day, the inside of a vehicle can become dangerously hot in a very short time.
For example, when it’s just 22°C outside, the temperature inside a parked car can soar to 47°C within an hour. That’s hotter than most ovens and can cause serious suffering, permanent damage or even death for a dog trapped inside.
What to do if you see a dog in a car on a warm day
1. Assess the dog’s condition.
Are they panting heavily? Drooling? Lethargic, distressed, or unresponsive? If a dog is showing any signs of heatstroke, call 999 immediately.
2. If the situation is critical and police haven’t arrived, be aware of the risks.
You may feel the need to break the window to free the dog. However, this could be classed as criminal damage. Legally, you must be able to justify your actions – and that you believed the car owner would have consented, had they known the dog was in danger.
3. If you decide to act:
-
Inform the police of what you intend to do and why
-
Take video or photo evidence of the dog’s condition
-
Get names and numbers of any witnesses
Remember: RSPCA officers do not have the power to break into vehicles – this must be done by the police.
What to do once the dog is free
If the dog appears to be in distress or shows signs of heatstroke, follow emergency first aid steps immediately. This can save their life.
-
Move the dog to a cool, shaded area
-
Pour cool (not cold) water over them
-
Offer small amounts of water to drink
-
Call a vet urgently
What if the dog seems OK?
If the dog isn’t showing signs of distress, here’s what you can do:
-
Try to find out how long they’ve been in the car. A pay-and-display ticket might help.
-
Note the car’s registration number.
-
If at a shop, venue or event, ask staff to make an announcement.
-
Stay with the car and keep an eye on the dog.
-
Be ready to call 999 if their condition worsens.
You can also ring the RSPCA cruelty line on 0300 1234 999 for advice – but if a dog is in danger, 999 should be your first call.
Even on a cloudy day, even for “just a few minutes” – a parked car is no place for a dog. Please help us spread the word and protect dogs from preventable suffering.
