The summer heat can be stifling for both dogs and humans. And when we lose power, it’s not only stressful on our own bodies but on our dogs’ as well. There are a few steps you can take to keep you and your dog safe and cool in extreme heat.

Why Dogs Struggle in Hot Weather
Unlike humans, dogs aren’t built to release heat efficiently. Most breeds are designed to conserve warmth rather than dissipate it, which makes high temperatures especially dangerous.
Dogs don’t have sweat glands the way humans do. Instead, they release heat through their paw pads and by panting. Because their bodies are mostly covered in fur, they retain heat more easily and can quickly become overheated, especially in extreme conditions or enclosed spaces.
Which Dogs Face Higher Heat Risk?
All dogs can struggle in the heat, but some are more vulnerable than others. Coat type, color, and density all play a role in how a dog handles high temperatures.
Light-colored or fine-coated breeds, such as Bull Terriers and Greyhounds, are more prone to sunburn. On the other hand, dogs with dark coats, like the Schipperke, absorb more heat from sunlight, increasing their risk of overheating and heatstroke. These differences make it especially important to tailor cooling strategies to your dog’s specific needs.
How to Help a Dog Cool Down
Along with plenty of cool water, the most important thing to do to keep a dog cool is to stay indoors or in the shade. If your air conditioning turns off on an extra-hot day (and you can’t get it back on), go to the coolest area of the house you can, such as the basement. If possible, stay at a friend’s house until your air conditioning is restored.
Having the right dog cooling supplies on hand can help. Consider stocking:
- A battery-operated fan
- Cooling cloths. If you keep your cool cloth in a cooler, don’t put it directly into the ice. You don’t want to put anything ice-cold onto a dog, because that shrinks the blood vessels and actually generates more internal heat.
- A cooling vest, which deflects the heat and cools the dog through evaporation
- A cooling crate pad or a cold, damp towel spread on the ground. Your dog can lie or stand on it to help release heat through their paw pads.
- Rubbing alcohol, which you can dab behind your dog’s ears, on their stomach, or on their paws. Rubbing alcohol cools faster than water and can draw out heat.
- A spray bottle filled with cool water. Spray the underside of your dog’s body that’s not exposed to the hot sun (such as the groin area, where the hair is less dense), the bottoms of their feet, and inside their mouth.
- A dog-safe thermometer. Your dog’s temperature shouldn’t rise above 102.5 degrees Fahrenheit, which is the high end of normal.
- Unflavored pediatric electrolyte solution for the dog to drink if they get dehydrated
Watch for These Signs of Heatstroke
Despite your best efforts, your dog could develop heatstroke. Here are some of the symptoms to look out for:
- Unusual breathing (rapid and loud)
- High rectal temperature (103 degrees Fahrenheit or higher)
- Extreme thirst
- Weakness and/or fatigue
- Frequent vomiting
- Disorientation
- Dark or bright red tongue and gums
- Skin around the muzzle or neck doesn’t snap back when pinched, which can be a sign of dehydration
- Difficulty breathing
- Thick saliva
- Rapid heartbeat
- Heavy drooling
- Agitation
What to Do if Your Dog Overheats
If you suspect your dog is overheated, immediately move them somewhere cooler and separate their fur with your fingers so cool air can reach the skin. To cool your dog down as quickly as possible, pour cool water over their head and body, gently hose a very gentle stream of cool water over them, or, where possible, submerge them in a tub of cool water.
Even if your dog seems stable, it’s a good idea to contact your veterinarian, who can advise you on whether your dog needs to be evaluated and, if necessary, treated for heatstroke.
Key Takeaways
- Dogs overheat quickly because they rely on panting and limited sweating to regulate temperature.
- Staying in shaded or cooler indoor spaces is the most effective prevention.
- Cooling tools like fans, damp cloths, and cooling mats can help lower body temperature safely.
- Heatstroke symptoms require immediate attention and gradual cooling.
- Always consult a veterinarian if overheating is suspected.
Frequently Asked Questions
-
What temperature is too hot for dogs indoors?
+
Dogs can begin to struggle when indoor temperatures climb into the high 80s. Without ventilation or cooling, heat can build quickly and lead to overheating, especially for high-risk breeds.
-
Can I use ice or very cold water to cool my dog?
+
No. Ice or extremely cold water can constrict blood vessels and slow heat release. Use cool, not cold, water for safe and effective cooling.
-
How do I know if my dog is dehydrated?
+
A common sign is reduced skin elasticity—if the skin doesn’t quickly return to place when gently pinched, your dog may be dehydrated. Dry gums and excessive panting can also be indicators.
-
Are fans enough to keep dogs cool?
+
Fans help circulate air but aren’t sufficient on their own in extreme heat. They should be used alongside hydration, shade, and cooling surfaces.
-
Should I call a vet after heat exposure even if my dog seems fine?
+
Yes. Heatstroke symptoms can appear later. It’s always safest to consult a veterinarian after a suspected overheating episode.
