Press the back of your hand flat against the surface and hold it there for seven seconds. If you cannot keep it down comfortably for that long, your dog should not be walking on it. Paw pads are tough against abrasion and they are not armor against heat.
Air temperature is a poor guide on its own. Asphalt absorbs sunlight and holds it, so pavement can run far hotter than the day feels, and it stays hot well after the sun has moved off it.
A Quick Note
This article covers prevention rather than treatment. Burned paw pads need veterinary attention, and signs include limping, licking or chewing at the feet, refusing to walk, or visible redness, blistering, or darkened patches on the pads. Contact a vet rather than treating burns at home.
Quick Answer
Use the seven-second hand test on the actual surface you will be walking on. Asphalt runs much hotter than air temperature suggests, especially in direct sun in the middle of the day. Walk early or late, stay on grass where possible, or carry your dog across short hot stretches.
Key Points
- The back of the hand for seven seconds is the standard check
- Asphalt absorbs and holds heat far beyond air temperature
- Dark surfaces in direct sun get hottest and stay hot longest
- Paw pads resist abrasion, not heat
- Surfaces stay hot for hours after the sun passes
- Burns often show up hours later rather than immediately
Surfaces Ranked by Heat
| Surface | How it behaves | Midday in summer |
|---|---|---|
| Asphalt and dark tarmac | Absorbs most, holds heat longest | Avoid |
| Dark concrete and brick | Hot, cools slightly faster than asphalt | Test first |
| Light concrete | Reflects more, runs cooler | Test first |
| Sand | Gets very hot on the surface | Avoid |
| Artificial turf | Hotter than people expect | Test first |
| Grass | Stays close to air temperature | Fine |
| Shaded dirt or bark | Coolest option | Fine |
Running the Test Properly
Use the back of your hand rather than the palm. Palms are calloused and less sensitive, which is exactly the wrong instrument for judging what a paw pad will feel.
Test the surface you will actually cross, not the shaded patch by your door. Heat varies enormously between sun and shade over a few feet, and the stretch in full sun is the one that matters.
Five to seven seconds is the window. If you are counting down and wanting to lift your hand, that is your answer, and there is no need to prove anything by holding it longer.
How I Handle It
The floor immediately outside my apartment is made not to hold heat, so that section is fine even in the middle of the day. Between there and the field where we go, there is a stretch of pavement, and that stretch is the problem.
If it is midday and the sun is beaming, I pick her up and carry her across the pavement, then put her down on the grass. That is the whole system. It is not sophisticated and it takes about fifteen seconds.
I do it specifically to avoid using booties. She is a small dog, the hot section is short, and carrying her is faster than getting footwear on and off twice a walk. Anyone with a bigger dog or a route that is mostly pavement would need a different answer, because this only works because both those things are true for me.
What I would say is that knowing exactly where the hot stretch is turned out to matter more than any general rule about temperature. I do not check the forecast, I know which fifty feet of the walk is the issue and I plan around that piece.
My experience is in a hot dry climate with a small dog on a short predictable route. It does not cover long walks on pavement, large dogs who cannot be carried, or humid climates, where the heat behaves differently.
Why Paw Pads Are Not Protection
Pads are built to handle rough ground, not high temperatures. The toughness that lets a dog cross gravel does very little against a surface hot enough to burn.
Dogs also do not always react immediately. A dog focused on a walk may cross hot ground without obvious distress and show damage hours later, which is why owners often miss the moment it happened.
Damage develops in layers. Redness and tenderness come first, blistering and loose pad tissue later, and a dog who seemed fine on the walk can be limping by evening. Related paw behavior is covered in why dogs lick their paws.
Timing Beats Everything
Early morning is the safest window, since surfaces have had all night to release heat. Late evening is second best and less reliable, because asphalt that baked all afternoon stays warm long after sunset.
The hottest ground does not coincide with the hottest air. Surfaces peak later, so a walk at four or five in the afternoon can meet hotter pavement than one at noon even though the air has started cooling.
Shifting walk times is the cheapest fix available and the one that removes the problem rather than managing it. Wider hot-weather guidance sits in walking a dog in hot weather.
Options When You Cannot Avoid It
Carrying
Works for small dogs over short stretches and nothing else. Simple, free, and limited by size and distance.
Booties
The real answer for longer pavement routes or larger dogs. Most dogs need a period of getting used to them, so introducing them indoors before a hot day matters. Options sit in booties for hot pavement.
Route changes
Grass verges, shaded paths, and dirt tracks all stay close to air temperature. Often a slightly longer route on grass beats a direct one on asphalt.
Paw balm
Conditions and protects pads from drying and cracking. It is not heat protection, and treating it as such is a mistake. Detail sits in paw balm.
Signs of a Burn
Limping or refusing to walk after time outside is the clearest sign, along with licking or chewing at the feet more than usual.
Look at the pads directly. Redness, blistering, patches darker than the surrounding pad, or pad tissue that looks loose or peeling all indicate damage. Missing sections of pad are a serious injury.
Any of these warrant a vet rather than home treatment. Burns get infected, dogs lick the affected area constantly, and the pain is worse than the appearance suggests.
Safe Versus Not
Safe looks like grass, shaded dirt, early morning walks, or any surface that passes the seven-second test. Cool ground and a comfortable dog need no further thought.
Not safe looks like asphalt in direct sun, artificial turf at midday, sand on a hot day, or any surface you cannot hold your hand against. Air temperature in the twenties does not make pavement safe, and that gap is what catches people out. Broader summer preparation sits in cooling vests for summer.

Frequently Asked Questions
How do I test if pavement is too hot?
Press the back of your hand flat against the surface for seven seconds. If you cannot hold it there comfortably, it is too hot for paws. Use the back of the hand rather than the palm, which is less sensitive.
At what air temperature does pavement become dangerous?
There is no reliable threshold, because asphalt in direct sun runs far hotter than the air. Mild-sounding days produce dangerous surfaces under strong sun, which is why testing the actual surface beats checking a forecast.
Are paw pads tough enough to handle hot ground?
They are built for abrasion rather than heat. The toughness that handles gravel offers little protection against a surface hot enough to burn, and damage frequently appears hours after the walk.
What time of day is safest for walks?
Early morning, since surfaces release heat overnight. Ground stays hot long after the air cools, so late afternoon can be worse than midday even when the temperature has started dropping.
Do dog booties work for hot pavement?
Yes, and most dogs need time to accept them. Introducing them indoors on a cool day works better than putting them on for the first time when you need them.
Is grass always safe?
Natural grass stays close to air temperature and is generally fine. Artificial turf is a different matter and gets considerably hotter than people expect, so it deserves the same test as pavement.
When should I see a vet?
If your dog limps, refuses to walk, or licks and chews at their feet after being outside, or if pads look red, blistered, darkened, or peeling. Burned pads need veterinary treatment rather than home care.
Surface checks matter away from home too. taking a dog on trips covers the wider planning.
