Police have raised concerns after numerous reports of dogs being locked in cars during high temperatures.

North Wales Police has continued to receive reports of people leaving their dogs in locked cars, as temperatures are set to rocket to 29C in some parts of Wales this week.

Temperatures in can rise significantly once they are stationary, which can be life-threatening for pets who are unable to get out.

North Wales Police tweeted: "We are still receiving numerous calls to report people leaving dogs locked in cars.

"Please do not leave your dog in your car, even with the window slightly open, the temperature inside your vehicle can increase within minutes."

This comes days after the RSPCA urged dog-owners not to leave dogs in cars in hot temperatures.

RSPCA Cymru superintendent Martyn Hubbard said: "There is a very serious side to keeping pets cool over summer as animals can suffer from heatstroke which could be fatal, especially if left in a hot car, conservatory or caravan.

“Pets may struggle to realise when they are too hot so make sure they have constant access to shade and don’t over exercise them in the heat. Remember if the pavement is too hot for your hand then it will be too hot for their paws.”
