These hot summer days, Shadow loves to run and play outside, but the hot weather can lead to heatstroke dangers in dogs as well as people. This week, we topped the thermostat at 101 degrees, and it will continue to hover near three digits all week long. Fun in the sun can quickly turn to tragedy if pet owners don’t take precautions to prevent cat and dog heatstroke dangers. Pet heatstroke is common because cats and dogs can’t effectively keep cool in hot summer weather. It becomes especially dangerous during summer travel in cars.
Hot weather dangers go beyond heatstroke dangers, though. Read about other reasons and ways to keep hot dogs and cats cool in this post.

How Hot Dogs & Cats Cool Off
Cats and dogs can’t sweat to cool off. For hot dogs, normal panting provides a rapid exchange of cool outside air, and evaporation off the tongue keeps dog temperature normal.
Cats rarely pant—they lick and groom themselves and the evaporation off of their fur helps keep them cool. If you see your kitty panting in hot weather, that’s a danger sign that your cool cat is too darn hot!
Some breeds are more at risk. Dogs and cats with smooshed-in faces like Pugs, Bulldogs, and Persians have a harder time cooling off even with panting. And when the outside air is the same or greater than pet’s normal body temperature of 101 to 102.5 degrees, deadly heatstroke develops.
Hot weather safety also includes keeping paw pads from burning, preventing sunburn, and even being aware of water intoxication — yes, that’s a thing! See more here.

Cars and Heat Stroke
Cars become deathtraps in even relatively mild temperatures. On a 78-degree day, a shaded car reaches temperatures of 90 degrees, but if parked in the sun, it will reach 160 degrees in minutes.
Leaving the car and air conditioning running is no guarantee of safety. Today, one of the most modern available for police dog safety is the computerized Hot-N-Pop system able to sense when the interior of the vehicle has become too hot for the K9 officer. When that happens, the system automatically rolls down the rear windows (windows have metal screens to prevent the dog from jumping out) and activates large window fans that bring in fresh air to help cool the dog. The Hot-N-Pop also activates the car’s emergency lights and horn, as well as signaling a pager or phone held by the canine handler.

Pets & Cars, What To Do
Of course, most pet parents don’t have a Hot-N-Pop system. So what do you do if you see a pet closed up in a car? I know the first impulse is to break the glass yourself, but you may not have the ability, the legality or resources to do that. Here’s what you can do.
- Use your phone–call animal control or dial 911. These folks have the authority not only to enter someone’s car but also to offer life-saving first aid.
- Also, go inside the nearest business–often a post office or grocery–and get the folks there to announce over the intercom for the pet’s person to get back to the car ASAP.
- Then stay with the care until you confirm that help has arrived.
Symptoms of Pets Heatstroke
Symptoms of mild heatstroke are body temperature of 104 to 106 degrees, bright red tongue and gums, thick sticky saliva, and rapid panting. When body temperatures go above 106 degrees, the pet’s gums become pale, he acts dizzy, bleeds from the nose or has bloody vomiting and diarrhea, and ultimately becomes comatose. These pets can develop disseminated intravascular coagulation (DIC) where the red blood cells blow up and can’t carry oxygen.
Getting the temperature down to 104 degrees or less is more important than rushing the pet to the emergency clinic—but severe cases DO need veterinary attention once you give first-aid. Rectal thermometers usually only register as high as 108 degrees and pets with severe heatstroke may have a body temperature that goes off the end and reaches 110 or higher.

Pet First Aid for Heat Stroke
For mild heatstroke, bring your puppy into an air-conditioned space and turn on a fan, so the outside temperature is lower than his body temperature and panting can work. Offer ice cubes to lick, or cold Gatorade or Pedialyte or water to drink, and wrap him in cold wet towels.

For severe heatstroke, soak the pet with cold water from the hose, or in the tub or sink. Place ice packs (bags of frozen peas work well) in his “armpit” and groin region where there are major blood vessels. The cold will chill the blood, and as it circulates, will cool the whole body from the inside.
Pets with temperatures at or above 107 degrees need a cold-water enema for even quicker cooling. Use a turkey baster or a contact lens solution bottle filled with ice water if you don’t have an enema bag. Grease the tip with petroleum jelly, K-Y or vegetable oil and insert the tip into the rectum and squeeze gently to fill the cavity with fluid. Once his temperature drops to 104, wrap him up in a towel and get him to the emergency room.

Prevent Heatstroke
It’s even better to prevent heatstroke in pets by providing shade and lots of cool water, or simply keeping pets inside. NEVER leave pets unattended in cars—that’s just asking for disaster. Prevent pet dehydration. Make sure your pets stay hydrated during hot weather. Water works best. There are also pet electrolyte products that combat dehydration with beef or chicken flavored solutions, like Petralyte.

My husband and I were at the mall a few summers ago. As we were walking back to our vehicle we noticed a small dog panting in an enclosed vehicle. Another car pulled in beside that vehicle and noticed the poor pup also. I called the police to report it. As I was on the phone with police, a family walked up to the car. I told the guy that the police were on their way, not to leave. He wanted to know why he couldn’t leave. We all told him that you don’t leave an animal in a hot car. He told us to mind our own business. I told him that I am minding my own but was speaking on behalf for the dog. The police arrived and once I realized that they didn’t need to speak to us, we left. We don’t know what happened with the poor dog. I am hoping that the guy got at least a fine.
Thanks for speaking up on behalf of the dog, Wanda!
Helpfull information!! I did know about the HOT N POP. I will add it to my FREE report on heatstroke.
