Some people enjoy taking their dogs along on errands, but leave them in the car. This can be deadly. A little heat outside the car can quickly make it very hot inside. On a summer's day of only 85 degrees, for example, even keeping the windows slightly open won't stop the inside temperature from climbing to 102 degrees in 10 minutes, to 120 degrees in 20 minutes. A dog whose body temperature rises to 107-108 degrees will, within a very short time, suffer irreparable brain damage - or even death. Never leave your dog alone in a car, even for a few minutes, in the summer months.

If you see a dog alone in a hot car, write down the car’s model, make, color and license plate number. Attempt to have the animal's guardian paged in the nearest buildings and call the police. Don’t leave the scene until the dog has been rescued.

If the authorities are too slow or unresponsive and the animal’s life is in imminent danger, find witnesses who will back up your assessment and remove the dog from the car. Explain the circumstances to authorities when they arrive.

Heatstroke symptoms to look for are thick saliva, heavy panting, lethargy, restlessness, dark tongue, vomiting, bloody diarrhea, lack of coordination, excessive thirst, lack of appetite, rapid heartbeat and fever.

Provide the dog with drinking water. Spray the dog with water, immerse him in a tub of cool (but not iced) water for a couple of minutes, or apply wet towels to the stomach, chest, paws and groin area. Do not use ice or cold water, and don’t overcool the dog.

If the dog shows any symptoms of heatstroke, get her to a veterinarian immediately.
