Keeping dogs cool in hot weather starts with reducing how much heat they have to cope with in the first place. When you’re travelling through an Australian summer, that means choosing cooler times to drive, walk and explore, keeping fresh water and shade available, maintaining airflow, avoiding hot surfaces and reducing activity when conditions heat up.
There isn’t one temperature that tells you whether a travel day is safe for every dog. Humidity, direct sun, airflow, hot ground, activity levels and how long your dog is exposed to the conditions all affect heat risk. Your dog matters too. Age, breed, coat, fitness, health and how well they cope with heat can change what works on any given day.
Cooling mats, fans and other gear can help with comfort, but they can’t make unsuitable conditions safe. Before sticking to the day’s itinerary, look at the conditions and your dog together. If they’re already struggling to stay comfortable, the better option may be to shorten an activity, move it to a cooler time or change the plan altogether.
How to Keep Dogs Cool in Hot Weather
Keeping dogs cool in hot weather starts with limiting heat exposure before they become uncomfortable. Choose cooler conditions for walks and outdoor activities, provide fresh water, shade and airflow, avoid hot surfaces and reduce activity when the day heats up.
Watch how your dog is coping as the day changes rather than relying on the forecast alone. If they are struggling to stay comfortable, give them somewhere cool to rest and be prepared to shorten, move or postpone the next activity.
There Isn’t One Safe Temperature for Every Dog
It can be tempting to look for one temperature that tells you when it is too hot for your dog, but there isn’t a universal cut-off that works for every dog or every situation.
Heat-related illness can occur at lower temperatures when other factors increase the heat load. Humidity, direct sun, heat radiating from roads and other surfaces, poor airflow, physical activity and how long your dog is exposed all affect how well they can cope.
This is why fixed rules such as 28°C, 30°C or 32°C can be misleading. A lower temperature does not automatically mean conditions are suitable, particularly if your dog is exercising in full sun, walking on hot ground or spending time somewhere with little airflow.
Humidity and Airflow Can Change How Your Dog Copes
Dogs rely heavily on panting to lose heat. When conditions are hot and humid, that cooling process becomes less effective. Still conditions with poor airflow can make it harder again, particularly during exercise or after your dog has already built up heat.
Check the humidity and the conditions your dog will actually experience, not just the maximum temperature on the forecast. A shaded rest stop with good airflow is very different from an exposed walk in full sun, even when the air temperature is the same.
Some Dogs Need More Conservative Plans
Brachycephalic dogs, older dogs, puppies, overweight dogs, thick-coated dogs and dogs that are unfit or not accustomed to warmer conditions may be at greater risk in hot weather. Dogs with respiratory, cardiovascular or other health concerns may also need more conservative travel and exercise plans.
These risk factors do not mean other dogs are protected from heat-related illness. Any dog can struggle when the combination of heat, humidity, activity and exposure becomes too much.
If your dog has a health condition that could affect how they cope with heat, speak with your veterinarian about what is appropriate for them before travelling in hot weather.
Instead of asking only, “How hot is it?”, consider the conditions, the activity, how long your dog will be exposed and how well that particular day works for the dog you are travelling with.
Plan Your Travel Day Around the Cooler Conditions
On hot travel days, timing can make a big difference. Where conditions allow, plan walks, active outings and exposed stops for cooler parts of the day, and use hotter periods for driving or resting somewhere your dog can stay properly cool.
That might mean walking earlier, choosing a shaded route, shortening an outing or moving an exposed activity to another time. On some days, you may need to skip an activity altogether rather than trying to make the original itinerary work.
Don’t assume early morning or evening will automatically be cool enough. Humidity can remain high, exposed surfaces can hold heat and conditions vary from place to place. Check what your dog will actually be walking into before you set off.
Check the Ground Before Your Dog Walks on It
Bitumen, concrete, sand and exposed surfaces at campsites and rest areas can become much hotter than the surrounding air. Before your dog walks or settles on them, place the back of your hand or your bare foot on the surface for several seconds. If you can’t keep it there comfortably, choose another surface or wait for conditions to cool.
Treat this as a practical check rather than a precise temperature test. Surface heat varies with the material, direct sun and local conditions, so air temperature alone won’t tell you how hot the ground has become.
Where possible, choose grass, shaded tracks or other cooler surfaces, and remember to check again later in the day rather than assuming a surface that was comfortable earlier will stay that way.
How to Keep Your Dog Cool in the Car
During hot-weather road trips, keep your dog inside the vehicle cabin where you can maintain a cool, well-ventilated environment. Use air-conditioning as needed and make sure airflow reaches the area where your dog is travelling, rather than assuming the temperature in the front of the car reflects conditions throughout the cabin.
Plan regular stops for water, toileting and a chance to rest somewhere cool. At each stop, watch how your dog is coping before continuing. If they are panting heavily or struggling to settle, give them time in suitable cooling conditions rather than treating the stop as a quick break before getting back on the road.
Air-conditioning can help manage the cabin temperature, but it doesn’t remove the need to monitor your dog. Direct sun through the windows, the length of the drive and your dog’s individual ability to cope with heat can still affect how comfortable they are.
A Parked Car Is Never a Cooling Setup
Never leave your dog unattended in a parked vehicle. Cars can heat up quickly, including on relatively mild days, and parking in the shade or cracking the windows does not make the vehicle safe.
Reflective covers, portable or solar-powered fans and cooling mats do not make it safe to leave a dog unattended in a parked car either. These products may help with comfort when used appropriately while you are travelling or staying with your dog in a properly ventilated environment, but they are not protection against a vehicle heating up.
If you need to stop somewhere your dog cannot come with you, plan for that before you arrive rather than relying on the car as a temporary waiting place.
Make Road Trip Stops Actual Cooling Breaks
A quick toilet stop isn’t necessarily enough if your dog has become hot during the drive. Choose genuine shade, get them off hot bitumen or concrete and offer fresh water. Keep activity low and give them time to settle somewhere cooler before heading back to the car.
Use the stop to check how your dog is coping. Pay attention to their panting, behaviour and willingness to move, rather than assuming a few minutes out of the car means they are ready to continue.
Before you leave, think about what comes next. If your dog is still struggling to settle or the next activity involves more heat, sun or exercise, it may make sense to shorten it, move it to a cooler time or change the plan.
Keeping Your Dog Cool at Camp
At camp, set up a shaded, well-ventilated resting area where your dog can get away from direct sun. Keep fresh water within easy reach and, where possible, out of the sun so it doesn’t heat up unnecessarily.
Check the ground and your dog’s sleeping area too. Exposed dirt, sand, concrete and other surfaces can become hot during the day, even if they were comfortable when you arrived. Shade also moves as the sun changes position, so a good setup in the morning may be exposed a few hours later.
During hotter periods, reduce activity or move walks and play to cooler conditions. Check the campsite throughout the day to make sure your dog can still reach suitable shade, water and a comfortable place to rest.
Cooling Gear Can Help at Camp
Cooling mats and raised beds can provide another resting option, while fans may improve airflow where appropriate. Use them alongside reliable shade, fresh water and a campsite setup that gives your dog somewhere comfortable to rest.
Camping adds its own hot-weather challenges, from moving shade to exposed campsites and limited access to cool indoor spaces. For a deeper look at planning around those conditions, read Camping With Dogs in Hot Weather.
Cooling Gear Helps, but It Doesn’t Make Unsafe Conditions Safe
Cooling mats, fans, cooling bandanas or vests, portable water bowls and shade equipment can all support your dog’s comfort in hot weather. Depending on how you travel and what your dog is comfortable using, they can provide a cooler place to rest, improve airflow, make water easier to offer or add shade when you stop.
Cooling gear works best as part of an already sensible hot-weather plan. It can’t make unsuitable conditions safe or compensate for too much heat, sun or activity.
A cooling mat, vest or fan isn’t a reason to continue a hot walk, stay longer in an exposed location or leave your dog in a parked vehicle. If your dog is struggling with the conditions, change the activity or environment rather than relying on equipment to compensate.

Signs Your Dog May Be Getting Too Hot
Watch for changes in your dog rather than waiting for an obvious emergency. Persistent or heavy panting, excessive drooling, seeking shade or cooler surfaces, restlessness, reluctance to continue, weakness or wobbliness can all be signs that your dog is struggling with the heat.
What to Do if Your Dog Is Getting Too Hot
Stop the activity and move your dog somewhere cool and safe. Offer access to fresh water and start appropriate cooling if needed. Give them time to settle and reassess the rest of the day rather than automatically continuing with the original plan once they appear more comfortable.
When It May Be More Serious
Vomiting, diarrhoea, confusion, collapse, seizures or being unable to stand can indicate a more serious heat-related emergency. If you suspect heatstroke, seek urgent veterinary attention.

Sometimes the Better Decision Is to Change the Plan
You can do plenty to help your dog stay cooler, but there will still be days when the conditions don’t work for what you planned. Cooling gear, shade and extra water can help manage heat, but they can’t make every activity appropriate for every dog.
Changing the plan doesn’t have to mean losing the whole day. You might shorten a walk, skip a midday activity, choose a shaded alternative or spend the hottest part of the day resting somewhere cool. If a stop is more exposed than expected, leave earlier or change where you go next.
Sometimes a bigger change is needed. An activity may need to move to another day, or part of the itinerary may need to be dropped altogether. What matters is making that decision based on the conditions your dog is actually experiencing rather than feeling committed to a plan you made before the day heated up.

Q1. What temperature is too hot for dogs?
There isn’t one temperature that is universally safe or unsafe for every dog. Humidity, direct sun, airflow, activity, hot surfaces and how long your dog is exposed can all affect how well they cope. Age, breed, coat, fitness and health can also increase heat risk, so consider the conditions your dog will actually experience rather than relying on one temperature threshold.
Q2. How can I cool my dog down in hot weather?
Stop strenuous activity, move your dog to a cooler or shaded area and provide access to fresh water. Appropriate cooling and airflow can also help your dog cool down. If your dog shows signs of serious heat-related illness or you suspect heatstroke, seek urgent veterinary attention rather than relying on everyday cooling measures alone.
Q3. Should I walk my dog in hot weather?
Where conditions allow, walk during cooler periods and choose shaded routes where possible. Check the ground before your dog walks on bitumen, concrete or sand, and reduce the length and intensity of the walk in warmer conditions. Consider humidity and direct sun as well as temperature, and watch how your dog is coping. If the conditions don’t work for your dog, postpone the walk or replace it with a cooler activity.
Q4. How do I keep my dog cool while camping?
Provide a shaded, well-ventilated resting area, keep fresh water accessible and check that the ground and sleeping surfaces aren’t becoming too hot. Reduce or reschedule activity during hotter periods and remember that shade can move throughout the day. For more detailed planning, read Camping With Dogs in Hot Weather.
Q5. Do cooling mats keep dogs safe in hot weather?
Cooling mats can provide a cooler surface for your dog to rest on, but they can’t guarantee safety or make unsuitable conditions appropriate. Use them alongside shade, water, airflow and sensible activity planning, and change the plan if your dog is struggling with the heat.
Conclusion
Keeping your dog cool in hot weather starts with planning around the conditions they will actually experience. Check the heat, humidity, sun, surfaces and planned activity, then adjust the day to suit how your dog is coping.
Even with careful planning, dogs can still become too hot. Knowing the early warning signs and what to do next matters, particularly if overheating becomes more serious.
