Cars are Ovens!

So it's Spring/Summer time and it is heating up fast.  This past weekend while going into the Harmon's grocery store by our home, Royce and I noticed 2 dogs inside a big white truck.  Yes the windows were cracked a little, but the temperature outside was above 72.  The temperature in a car is usually 10 to 30 degrees hotter than the outside temperature. The color of your car adds to this (i.e. black).  Put on a winter coat and sit in a car for a while and see how it feels.  Even on a cool 72 degree day, the inside of the car can get well over 90 degrees...without the coat on. Dogs temperatures already run hotter than humans.  Cracking the windows doesn't cut it.


You should never leave your dog in a vehicle even if the windows are down, if the temperature is above 69 outside. 

Found this website that has awesome "Hot Car Flyers" to leave on peoples cars.  Also had some great articles.

1. Dogs are especially vulnerable to heat-related illness because they can only cool off by panting and through the pads in their feet.

2. Even on seemingly mild days, an enclosed car can be deadly. In a Stanford University study, when it was 72 degrees outside, a car’s internal temperature climbed to 116 degrees within one hour.

3. Enclosed cars heat up quickly. In a study by San Francisco State University, when it was 80 degrees outside, the temperature inside a car rose to 99 degrees in 10 minutes and 109 degrees in 20 minutes.

4. A dog’s normal body temperature is between 101 to 102.5 degrees; a dog can only withstand a high body temperature for a short time before suffering nerve damage, heart problems, liver damage, brain damage or even death.

5. Studies show that cracking the windows has little effect on a car’s internal temperature.

Already this year, UAN has received reports of dogs like Snuggle, a Maltese/Lhasa Apso who was locked in a car while her owner visited a Tampa, Florida amusement park. When Snuggle was rescued, the temperature inside the car was more than 90 degrees and her core temperature was nearly 106 degrees.

Have you ever noticed how hot it can get inside a car on a summer day — far hotter than it is outside? That's because a car acts like a greenhouse, trapping the sun's heat.

A study by the Animal Protection Institute showed that even moderately warm temperatures outside can quickly lead to deadly temperatures inside a closed car.

The study, conducted during a local heat wave, compared an outside temperature of a shaded area with the inside of an automobile in three states: fully closed, with four windows cracked, and with two windows cracked. Inside temperatures were measured with an indoor/outdoor thermometer and an oven thermometer (both readings are given). All temperatures use the Fahrenheit scale.

"Never leave your pet alone in a car during hot weather. Culturally, dogs are more a part of our life and our lifestyle than ever before — going along for a ride in the car, whether running errands or on the family vacation. Just as with children, we must be aware of the danger in leaving our dog inside a parked car in the summer heat. Simply parking in the shade or leaving the windows cracked is not enough. Windows collect light and trap heat inside the car, sending the temperature to dangerous and deadly levels rapidly. In many states, it’s against the law to leave a pet unattended in a parked vehicle in a manner that endangers the health or safety of the animal.

A car’s inside temperature can increase as much as 40 degrees in an hour — with 80 percent of that increase within the first 30 minutes. On an 85-degree day, the temperature inside a car with the windows cracked slightly can reach 102 degrees within 10 minutes!

Carry two car keys with you, so if you have to leave your dog in the car for even a few minutes, you can leave the engine running and the air conditioning on, with your dog inside and the doors locked. Take the second key with you so you can open the door when you return. And if you see a pet in a parked car on a hot summer day, go to the nearest store to have the owner paged, enlist the help of a security guard or call the local police."

I was very angry throughout the whole grocery shopping trip. I can't remember anything Royce asked regarding food/meals.  Sorry Royce :P  I have a one track mind sometimes.  What made me more angry, was this person didn't even do a quick run.  They were there when we pulled in and was still there when we left.  Don't even do a quick run into a store. A car can raise 15+ degrees in 10 minutes.
