![Never Leave Pets in a Hot Car]
Every summer, heartbreaking stories emerge of dogs suffering from heatstroke after being left in parked vehicles. Most owners never intend for it to happen, they think they’ll “just be a minute.” Unfortunately, a few minutes is all it takes for the inside of a vehicle to become life-threatening.
The image above tells a powerful story:
* On a 70°F day, your car can reach 89°F in just 10 minutes and over 104°F within 30 minutes.
* At 80°F outside, the interior can climb to 99°F in only 10 minutes and 114°F after 30 minutes.
* When it’s 90°F outside, temperatures inside your vehicle can soar to 109°F in 10 minutes and an astonishing 124°F in just half an hour.
Cracking the windows makes very little difference.
Why Dogs Overheat So Quickly
Unlike people, dogs cannot efficiently cool themselves by sweating. They primarily regulate their body temperature by panting and through the small sweat glands in their paw pads. When the surrounding air becomes too hot, panting is no longer effective.
This is especially true for:
* Puppies
* Senior dogs
* Overweight dogs
* Dogs with thick coats
* Brachycephalic (short-nosed) breeds
* Large breeds like Rhodesian Ridgebacks after exercise
Once a dog’s body temperature rises above approximately 104°F, heat exhaustion begins. If it continues climbing to 106°F or higher, vital organs can begin to fail, potentially resulting in permanent damage or death.
Signs of Heatstroke
If your dog has been exposed to excessive heat, watch for:
* Heavy or excessive panting
* Bright red or pale gums
* Thick, sticky drool
* Weakness or stumbling
* Vomiting or diarrhea
* Rapid heartbeat
* Glassy eyes
* Collapse or unconsciousness
Heatstroke is a medical emergency. Immediate veterinary care can save your dog’s life.
“I’ll Only Be Gone for a Minute”
Most tragedies happen because someone believed they would only be inside briefly.
Unfortunately:
* Long checkout lines happen.
* Unexpected conversations occur.
* Children need assistance.
* Phones ring.
* Emergencies arise.
Meanwhile, the temperature inside your vehicle continues climbing minute after minute.
There is no safe amount of time to leave your dog unattended in a parked car during warm weather.
Better Alternatives
Instead of bringing your dog along if they must remain in the vehicle:
* Leave them comfortably at home.
* Travel with another person who can stay with the dog while errands are run.
* Visit pet-friendly businesses where your dog can accompany you.
* Schedule outings during cooler morning or evening hours.
Your dog would much rather nap safely at home than risk overheating in a parked vehicle.
Rhodesian Ridgebacks and Heat
Many people assume Rhodesian Ridgebacks naturally tolerate extreme heat because of their African heritage. While they generally handle warm weather better than many breeds, they are not immune to heatstroke.
Ridgebacks are athletic, muscular dogs that generate significant body heat during activity. High humidity, hot pavement, lack of shade, or confinement inside a vehicle can quickly overwhelm their ability to cool themselves.
As responsible Ridgeback owners and breeders, we always recommend:
* Fresh water available at all times
* Plenty of shade
* Exercise during cooler parts of the day
* Never leaving them unattended in a parked vehicle
A Simple Rule That Saves Lives
If the temperature is warm enough that you wouldn’t sit inside a parked car without air conditioning, your dog shouldn’t either.
Every year, countless pets die from something that is completely preventable.
The safest choice is also the easiest:
When in doubt, leave your dog at home.
