Even if it’s for a short time with the windows partially open, dogs can get dangerously overheated in a vehicle. Cars can act like greenhouses, the glass trapping the heat from the sun, whether it’s sunny or not. Even on cloudy days or in the shade, the temperature in your vehicle can increase rapidly, leaving your best friend with no options for relief. This summer, if your dog is traveling with you, make sure you take water and a container they can drink from. If possible, ask travel mate to accompany the dog outside of the vehicle while you are parked.
