The RSPCA has issued advice on what to do if you come across a dog in a vehicle.

The advice said: "First, assess the dog's condition. If they're showing any signs of heatstroke dial 999 at once.

"If the dog's condition is critical, and the police haven't arrived yet, your instinct will be to break into the car to free them.

"But please be aware that this could be classed as criminal damage.

"You may need to defend your actions in court, so please be sure you're doing the right thing. 

"Legally, you can commit damage if you believe the car owner would consent to it if they knew the dog was in danger.

"If you're sure you need to free the dog, tell the police what you intend to do and why.

"Take photos or videos of the dog. Are there any other witnesses? Take their names and telephone numbers.

"Don't be afraid to dial 999. If it's an emergency, we may not be able to get to you - and the dog - quickly enough.

"And as we have no powers of entry, we'd need to ask the police to help us rescue the dog.

"Don't worry - the police will soon let us know if the dog needs our help."
