The Summer heat can be hazardous for dogs if owners don’t alter their routines to make sure their pets are never stuck in hot cars.  Despite common sense and a local ordinance, law enforcement gets a few emergency calls each week from people worried after seeing a dog left inside a car while its owner runs an errand.  Sometimes people do not realize how quickly the inside of a car will register extreme heat after a car is parked and turned off on a Summer day.  WUFT-TV’s Catherine Awasthi reports.
