Calls received about dogs left in cars on hot sunny days can be a challenge unless Garth happens to be very close to the reported location. Frequently, the car is gone when he arrives. If the car is still there, he will visually check the dog for any signs of distress or heat stroke, which are grounds for him to remove the dog from the car. If the dog is not in immediate danger, he waits at the vehicle and issues a warning to the owner.
