Keeping Your Dog Cool on Walks
Dogs overheat far faster than most owners realise—and unlike us, they can't just take off a layer or reach for a cold drink. Understanding how your dog actually cools down (or struggles to) is the key to making summer walks safe rather than risky.
This guide covers practical, actionable ways to keep your dog cool on a walk: timing, route choices, warning signs to watch for, and the gear that genuinely makes a difference.
Quick Answer
Walk during the coolest parts of the day (early morning or after sunset), stick to shaded or grassy routes over pavement, and bring water with you every time. A cooling vest and a portable water bottle make the biggest practical difference on hot days, since dogs cool down mainly through panting and their paw pads—not sweating like humans do. Always check the ground temperature before you set off, and know the early signs of overheating so you can turn back before it becomes an emergency.

Why Dogs Overheat Faster Than You'd Think
Unlike humans, dogs can't cool themselves by sweating across their whole body. They rely almost entirely on panting and a small amount of sweat through their paw pads—both far less efficient than human sweat glands. This means a dog can go from comfortable to dangerously overheated in the time it takes you to finish a normal-length walk.
Heat-related vet visits rise sharply during summer months. Dogs don't show discomfort the way humans do—many will keep walking, playing or running even as their body temperature climbs to dangerous levels, simply because they want to keep up with you.
This is exactly why prevention matters more than reaction—by the time a dog is clearly struggling, it's already had to work harder to cool down than it should. For more detail on safe walking temperatures, our guide on what temperature is too hot for dogs breaks this down further.
Best Times to Walk in Hot Weather
| Time of Day | Suitability | Notes |
|---|---|---|
| Before 9am | ✅ Best | Ground and air temperatures are at their lowest. |
| 9am–4pm (summer) | ❌ Avoid | Pavement can reach burn-inducing temperatures even when air feels mild. |
| After 7pm | ✅ Good | Ground has had time to cool from peak sun exposure. |
| Overcast but humid days | ⚠️ Caution | Humidity reduces how effectively panting cools your dog—don't assume "not sunny" means safe. |
Cooling Gear That Actually Helps
Not all "summer" dog products make a meaningful difference. These two genuinely help on hot walks:
| Product | How It Helps |
|---|---|
| Cooling vest | Soak in cold water before wearing—the evaporative effect keeps your dog's core temperature down throughout the walk, not just at the start. |
| Portable water bottle | Lets you offer water mid-walk rather than waiting until you're home, which matters since dehydration accelerates overheating. |
| Light, breathable harness | Reduces heat trapped against the body compared to bulkier equipment—worth checking if your current harness is doing this unintentionally. |
Introduce a cooling vest at home first, the same way you'd introduce any new harness—let your dog wear it briefly indoors so the sensation of a damp vest isn't a surprise on the first hot walk.
The Pavement Test
Press the back of your hand flat on the pavement and hold it for 7 seconds. If it's too hot for your hand, it's too hot for your dog's paws—burns can happen in under a minute on hot asphalt, even on days that don't feel extreme to you.
If the test fails, stick to grass, shaded trails, or wait until the ground has cooled. For a full breakdown of paw safety, timing, and burn symptoms, see our guide on how hot is too hot for a dog's paws.
Signs of Overheating vs Heatstroke
| Early Overheating (Act Now) | Heatstroke (Emergency) |
|---|---|
| Heavier panting than usual | Extremely rapid, distressed panting |
| Seeking shade or slowing down | Collapse or inability to stand |
| Bright red tongue/gums | Vomiting or diarrhoea |
| Excess drooling | Disorientation or seizures |
If you see any signs in the heatstroke column, stop the walk immediately, move your dog to shade, offer water, and contact a vet right away—heatstroke can become life-threatening quickly.
Which Breeds Are Most at Risk?
| Breed Type | Risk Level | Why |
|---|---|---|
| Flat-faced breeds (Bulldogs, French Bulldogs, Pugs) | ⚠️ High | Shortened airways make panting—their main cooling method—far less effective. |
| Thick or double-coated breeds (Huskies, Golden Retrievers) | ⚠️ High | Heavy coats trap heat close to the body, even if bred for cold climates. |
| Senior or overweight dogs | ⚠️ Elevated | Reduced cardiovascular efficiency makes regulating temperature harder. |
| Puppies | ⚠️ Elevated | Less developed temperature regulation and smaller reserves of body water. |
| Lean, short-coated adult dogs | Lower | Still requires normal precautions, but generally regulates heat most efficiently. |
Common Mistakes to Avoid
| Mistake | Better Approach |
|---|---|
| Judging heat risk by air temperature alone | Always check pavement temperature separately—it can be 30°C+ hotter than the air. |
| Waiting until your dog seems tired to offer water | Offer water at regular intervals throughout the walk, not just at the end. |
| Assuming a shorter walk is automatically safe | A short walk at midday can be riskier than a long one at 7am. |
| Skipping cooling gear on "just a quick walk" | Overheating risk isn't about walk length—it's about heat exposure and exertion combined. |

Frequently Asked Questions
What's the best time of day to walk a dog in hot weather?
Before 9am or after 7pm, when both air and ground temperatures are at their lowest. Avoid the 9am–4pm window during summer heat.
Does a cooling vest actually work?
Yes, when used correctly. Soaking it in cold water before wearing creates an evaporative cooling effect that helps regulate your dog's temperature throughout the walk, not just at the start.
How do I know if the pavement is too hot for my dog?
Press the back of your hand on the pavement for 7 seconds. If it's uncomfortable for you, it's too hot for your dog's paws.
What are the first signs my dog is overheating?
Heavier panting than usual, seeking shade, slowing down, or a brighter red tongue and gums. These are your cue to head somewhere cool and offer water immediately.
Which dogs are most at risk of overheating?
Flat-faced breeds, thick or double-coated breeds, puppies, seniors, and overweight dogs are all at higher risk and need extra precautions in hot weather.
Should I still walk my dog on very hot days?
You can, but shift walks to early morning or evening, keep them shorter, choose shaded or grassy routes, and bring water. On extreme heat days, a short garden session may be safer than an outdoor walk.
