Tesco confirmed it will be undertaking these precautions to make sure dogs are not left by owners in hot vehicles, Birmingham Live reports.
Tesco staff have been trained on what to look out for.
Tesco confirmed: "We're working with the RSPCA and all of our colleagues in store have received training to ensure animal welfare is protected.
"Our colleagues regularly patrol our car parks and are given guidance on what to do if they spot a dog unattended in a car."
The move comes as the UK heatwave is set to bring 31C temperatures today.
Emergency animal care provider Vets Now also warned rising temperatures could increase the risk of heat stroke in dogs.
The vet service sees a spike in callouts as the weather warms up and has warned that temperatures above 20C put dogs at risk, and that survival rates for dogs with heat stroke is just 50 per cent.
Dave Leicester, head of telehealth at Vets Now, said: "All dogs can overheat if left without water or in hot conditions for too long. So on hotter summer days it's best to walk your dog in the morning or evening when it's cooler."
