This summer the RSPCA have already been called to three incidents of dogs dying in hot cars.

Last year the charity dealt with 8,779 reports of dogs suffering from heat exposure, but what should you do if you see a poor pooch trapped in a car?

The RSPCA advise calling 999 as they might not be able to attend quickly enough and would need police assistance anyway.

A dog is in danger if it displays signs of heat stroke, which are panting heavily, drooling excessively, being lethargic or uncoordinated, or collapsed and vomiting.

If you break into the car to free the dog -if the police can not attend - this could be classed as criminal damage.

Before you do so make sure you tell the police of your intentions and take photos or videos of the dog, and names and numbers of any witnesses.

You have a lawful excuse to commit damage if you believe the owner would consent to the damage if they knew the circumstances.

Once you have rescued the dog from the car you should move it to a shaded or cool area and douse it with cool water.

You should also allow the dog to drink small amounts of cool water.

If the dog is not showing signs of heatstroke establish how long the dog has been in the car and make a note of the registration.

If you are in a shopping car park ask a member of staff to make an announcement over the tannoy.

Someone should stay with the dog to monitor its condition.
