It is really tragic that hundreds of dogs fall prey to this stupid incident when their owners leave them behind in a car. The owners do not even have an idea how hot can the car get and that it is extremely dangerous for the dog inside. They can suffocate to death so great care must be taken and if you see a dog trapped in a hot car, try doing the things given below.
Gather the necessary info such as the registration number of the car and it is better to take a picture of the license plate of the car with your smartphone.
Keep calm and notify other people and rush to a building nearby and inform the manager. Time is of the essence here because the dogs can suffer brain damage within just a minute or so.
Sometimes it is better to go to the backside of the car to watch the dog and do not leave your place.
When the owner arrives to their car, it is better to educate them about this and let them know how hot the car is.
If you have tried everything and the owner cannot be found, then it is better to call for help and dial 911 immediately.
