WBRZ - Baton Rouge

A dog trapped in a car in 90-degree heat in Pennsylvania honked the horn until he got his owner's attention to let him out. The owner ran an errand and forgot Max the Labrador was in the car when she got home. She says she heard the horn sound several times and looked out her window but saw nothing amiss. After it continued she went out and looked inside to find Max in the driver's seat with his paws on the horn. He was in the car about an hour. She took him to a vet after wetting him down and he's okay.
