We have all been told to NEVER leave our pets in the car for any extended period of the time during the summer months. Since many people don't take this warning too seriously, this vet decided to give a better example of what will happens when left in the car. If this doesn't wake you up, nothing will. 

You should NEVER leave your pets in the car during the summer. You are leaving them in a dangerous and life threatening situation.

This vet is trying his best to get this through our thick skulls. To make the point very clear, he puts himself into the very same situation as a pet left in the car.

Pay attention to this and make sure to NEVER again leave your beloved furry friend in the heat again.
