If you think you're doing your dog a favor by bringing him with you on hot summer days, think again.
The inside of the car heats up more quickly than you think, to levels that are dangerous for most dogs.
In a series of experiments over the course of the week, I left the car, with the thermometer in it, in various places, in various conditions, to see how quickly it would heat up.
'I just ran into the store to buy one thing'
In the first experiment, I left the car with the windows shut, in a parking lot for an hour. It was 83 degrees outside. Inside the car, it was 108.
'But I parked in the shade'
Second, I parked the car in the shade, with the windows cracked. It was 81 degrees outside. In two minutes, the temperature inside the car had jumped to 86 degrees. In 10 minutes, it had climbed to 90 degrees.
'But the windows were cracked open'
Third, I parked the car with the windows cracked. It was 83 degrees and overcast.
After five minutes, the temperature had climbed to 86 degrees.
In 10 minutes, the temperature inside the car was 90 degrees.
In 30 minutes, even with the clouds, and the windows open, the temperature inside the car had hit 100 degrees.
