Dog in Summer: 10 Tips to Prevent Heatstroke [June 2026]
Summer is finally here! June 2026 is treating us to plenty of sunshine, long days, and warm temperatures. But what means ice cream, swimming pools, and cozy barbecues for us can quickly become a serious health challenge for our four-legged friends. While we wear breathable clothing and sweat through our skin to cool down, dogs do not have this luxury.
Dogs have almost no sweat glands on their bodies. They only sweat a little through their paw pads. To regulate their body temperature, they rely primarily on one thing: panting. Rapid breathing creates evaporative cooling on the tongue and mucous membranes, which cools the blood. However, in extreme outdoor temperatures or high humidity, this internal cooling system quickly reaches its limits. The result: the dog overheats, and there is a risk of a life-threatening heatstroke.
As a responsible dog owner, it is up to you now. With a bit of caution, proper planning, and our field-tested advice, your furry friend will get through the hot season safely and comfortably. Here are our 10 most important tips for summer with a dog.
10 Tips for a Relaxed Summer with Your Dog
1. The Car Heat Trap: Even 20 Degrees Can Be Deadly
It cannot be said enough: Never leave your dog alone in the car during the summer! Even if you only want to pop into the supermarket "for five minutes," you are risking your pet's life. The University of Veterinary Medicine Hannover (TiHo) and the German Veterinary Chamber warn urgently: Even at an outside temperature of 20 degrees Celsius, the interior of a car can heat up to a life-threatening 46 degrees within an hour.
Many owners mistakenly believe that parking in the shade or leaving a window slightly open is enough to provide cooling. This is a fatal misconception. The sun moves, air exchange through a window crack is minimal, and temperatures rise by the minute. Once a dog’s body temperature exceeds 41 degrees, the proteins in the blood begin to coagulate—leading to brain damage and death. If you are running errands in the summer, it is best to leave your dog in the cool of your home.
2. Adjust Walk Times: Early Morning and Late Evening
The usual long walk during your lunch break will unfortunately have to be skipped during the summer. Shift your long walks to the early morning hours (ideally before 8:00 AM) and late in the evening (after 8:00 PM). At these times, the air is still pleasantly fresh, and the ground has either not yet heated up or has already cooled down.
During the day, short bathroom breaks in the shaded grass are completely sufficient. Make sure your dog does not overexert itself. If your four-legged friend is already panting heavily, it is time to head back and let them rest.
3. The 7-Second Test: Beware of Hot Asphalt
We humans wear shoes and often forget how scorching hot the pavement gets in the summer. For your dog's sensitive paw pads, asphalt can be pure torture. A study from Frostburg University has shown that asphalt can heat up to a staggering 52 degrees at an air temperature of 25 degrees. At 30 degrees in the shade, the ground can easily reach 60 degrees or more—temperatures that lead to severe second- or third-degree burns within seconds.
How to perform the 7-second test: Place the back of your hand flat against the sun-exposed asphalt for seven seconds. If it is too hot for you to keep your hand there, it is too hot for your dog. In this case, stick to meadows, forest paths, or light-colored paving stones in the shade.
4. Water, Water, Water: Stay Hydrated
Just like us, dogs need to drink much more in the summer to compensate for the fluid loss caused by constant panting. Ensure that there are always several bowls of fresh, cool (but not ice-cold!) water available at home. When you are on the go, a portable dog water bottle or a travel bowl is an absolute essential.
Tip: Some dogs are reluctant drinkers. You can encourage your dog by adding a splash of unsalted chicken broth or some wet food to their water. Fruit with high water content, such as a small piece of watermelon (without seeds or rind), is also a great, hydrating snack.
5. Cooling from Below: Wet Towels and Dog Pools
Since dogs barely sweat, they cool down best through contact surfaces with little hair—especially their belly and paws. A damp, cool towel for your dog to lie on often works wonders. Never drape the towel over your dog, however, as this can trap heat!
If you have a garden or a large balcony, a special dog pool made of sturdy material is a fantastic investment. Many dogs love splashing around in the water. Alternatively, a lawn sprinkler or a shallow stream during a forest walk works just as well.
6. Create Shady Spots and Avoid Direct Sun
Dogs instinctively know what is good for them and will often seek out cool places themselves when it gets hot—whether it is the cool tiles in the bathroom, the space under the dining table, or a shaded spot under a tree in the garden. Support your dog by ensuring these retreats remain accessible.
Never leave your dog tied up in direct sunlight. Special cooling mats that react to pressure and draw heat away from the body are also gratefully accepted by many dogs on hot summer days.
7. Summer Grooming: Brushing Instead of Shaving
Many owners think they are doing their dog a favor by shaving their coat completely in the summer. However, this is often a mistake! The coat of many dog breeds acts as natural insulation—it keeps them warm in the winter and protects them from heat and direct sunlight in the summer. A bald dog is extremely susceptible to sunburn.
Instead of reaching for the clippers, reach for the brush. Especially dogs with thick undercoats (like Golden Retrievers or German Shepherds) need to be brushed out thoroughly and regularly in the summer. When the dense, dead undercoat is removed, air can circulate against the skin again, providing enormous relief.
8. Reduce Activities: No Dog Sports in the Midday Heat
Agility, fetch, or running alongside a bicycle are great activities—but not in the middle of summer at 30 degrees. Physical exertion causes your dog's body temperature to rise rapidly. Skip strenuous dog sports and extensive ball games on hot days.
Instead, opt for quiet brain games in the cool living room. Scent games, practicing new tricks, or using snuffle mats will mentally tire your dog without putting stress on their circulatory system.
9. Caution with Short-Nosed Breeds (Brachycephaly)
Extra caution is required for brachycephalic (short-headed) breeds. Pugs, French Bulldogs, English Bulldogs, or Pekingese have anatomically narrowed airways. This significantly limits their ability to pant and therefore cool down.
For these dogs, even a short walk at 25 degrees can be life-threatening. If you would like to learn more about the specific needs and health challenges of different breeds, take a look at our comprehensive breed overview. With these dogs, pay meticulous attention to the slightest signs of exhaustion or respiratory distress.
10. Recognizing Heatstroke and Providing First Aid
Despite all precautions, emergencies can happen. Heatstroke is an absolute veterinary emergency that requires immediate action. According to the German Veterinary Chamber and the VDH, you can recognize a heatstroke by the following symptoms:
- Heavy, restless panting with the tongue hanging far out
- Deep red to bluish mucous membranes
- Increased salivation (often viscous)
- Apathy, staggering, or loss of balance
- Vomiting or diarrhea
- In the worst case: seizures and unconsciousness
First Aid Measures: Move the dog into the shade or a cool room immediately. Start cooling down at once—but slowly! Use lukewarm to hand-warm water, never ice-cold water. Ice water would cause blood vessels to constrict and block heat dissipation. Start at the paws and legs and slowly work your way up to the belly and neck. Offer the dog sips of lukewarm water, but do not force them to drink. Afterward, make your way to the vet or an animal hospital as quickly as possible—continue to keep the dog cool during the trip.
Frequently Asked Questions (FAQ)
At what temperature does it become dangerous for dogs?
There is no general limit, as it depends heavily on the breed, age, weight, and general health of the dog. In general, however, many dogs start to find the heat strenuous starting at about 20 to 25 degrees Celsius. From 28 to 30 degrees, it becomes critical for almost all dogs if they are exerting themselves or exposed to direct sunlight. Short-nosed breeds, senior dogs, or animals with cardiovascular conditions often suffer even at much milder temperatures.
Can dogs eat ice cream in the summer?
Yes, but with caution! Regular ice cream for humans is off-limits because it contains too much sugar, lactose, and often toxic ingredients like chocolate or xylitol (birch sugar). However, you can easily make healthy dog-friendly ice cream yourself. For example, puree some liverwurst, cottage cheese, or banana with water and freeze the mixture in a Kong toy or ice cube tray. Important: Let your dog lick the ice slowly. If they swallow large, ice-cold chunks, it can lead to painful stomach cramps or gastritis.
Should I have my dog shorn in the summer?
That depends on your dog's coat type. Dogs with an undercoat (e.g., Husky, German Shepherd, Golden Retriever) must never be shorn. Their guard hair protects them from UV radiation and heat. Here, only regular, thorough brushing of the undercoat helps. Dogs with continuously growing hair without an undercoat shed (like Poodles, Havanese, or Maltese) can and should have a shorter haircut in the summer, as their fur can become too thick. If in doubt, consult a professional dog groomer.
