There's a test every dog owner in Britain should know, and it takes seven seconds. Press the back of your hand flat against the pavement. If you can't hold it there comfortably for a slow count of seven, the ground is too hot for your dog's paws — and in a proper July heatwave, plenty of UK pavements start failing that test by mid-morning.
This guide covers everything behind those seven seconds: why pavements get so much hotter than the air, which surfaces are worst, when it's actually safe to walk, how to spot a burned pad, and how to keep paws in good shape all summer.
The quick answer
Use the seven-second test: press the back of your hand flat on the pavement for seven seconds. If it's uncomfortable for you, it's unsafe for your dog. On hot days, walk early in the morning or late in the evening, stick to grass and shade where you can, and check paws after every warm-weather walk. If pads look red, blistered or damaged, that's a vet call — not a wait-and-see.
How to do the seven-second test properly
- Use the back of your hand, not your palm — the skin there is thinner and closer in sensitivity to a paw pad than your work-hardened palm is.
- Press it flat against the actual surface you'll be walking on — the sunny stretch of tarmac, not the shaded doorstep where you're standing.
- Count a slow seven. If you flinch, pull away, or find yourself bargaining at five — the walk waits.
Test the worst surface on your route, not the best one. A walk that starts on cool flagstones in the shade can still cross a car park that's been roasting since breakfast.
Why the pavement is so much hotter than the air
The number on the weather app is the air temperature, measured in the shade. Tarmac sits in direct sun all day, absorbing heat and giving very little of it back — so the surface can run 20 to 30 degrees hotter than the air around it. UK animal charities have long warned that on a 25°C day, tarmac in direct sun can reach around 50°C, and at that temperature skin damage can happen in under a minute.
That's the trap of the British summer: 25°C feels like a pleasant day to us, in our shoes. Your dog is walking barefoot on a griddle.
A rough guide to how it scales:
- Low 20s (°C) air temperature: sunny tarmac can already be uncomfortably hot by early afternoon — test before you walk.
- Mid 20s: tarmac in full sun can pass 50°C — mid-morning to early evening walks need real caution.
- High 20s and above: most hard surfaces in direct sun will fail the seven-second test for much of the day. Walk at dawn and dusk, or swap the walk for garden games in the shade.
Which surfaces are worst for paws?
- Tarmac and asphalt — the worst offender. Dark, dense, and holds heat well into the evening.
- Artificial grass — looks innocent, gets shockingly hot in direct sun, and doesn't cool the way real grass does.
- Metal — drain covers, manhole lids, ramps and truck beds heat fast enough to burn quickly. Step around them.
- Sand — beach days count. Dry sand in full sun can be brutal on pads; the wet sand near the waterline is the safe lane.
- Paving stones and flagstone — generally a touch kinder than tarmac, especially lighter-coloured stone, but still very capable of failing the test in full sun.
- Grass and soil — your friends. Real grass stays dramatically cooler than any hard surface, and shaded grass cooler still.
Route-planning in a heatwave is mostly the art of connecting the green bits.
When to walk in a UK heatwave
- Early morning is the gold standard — surfaces have had all night to cool, and before roughly 8am even tarmac is usually reasonable.
- Late evening is second best — but test first: tarmac stores heat and can stay warm well after the air cools. An 8pm pavement can be hotter than an 8am one.
- The middle of the day is for shade, water and supervised lounging — not pavement miles. A skipped walk never hurt a dog; a burned pad always does.
On genuinely hot days, remember paws are only part of the picture — our guide on how to keep your dog cool in hot weather covers heatstroke signs, hydration and the rest of the heatwave playbook.
Signs your dog's paws are burned
Dogs are stoic, and pads are hard to see mid-walk — so watch behaviour as much as the paws themselves:
- Limping, lagging behind, or refusing to walk on a surface they normally trot across
- Excessive licking or chewing at the feet during or after a walk
- Pads that look red, darker than usual, or shiny
- Blisters, loose flaps of pad, or raw patches — these are serious
- Whimpering or flinching when a paw is handled
What to do if you suspect a burn
- Get off the hot surface — carry your dog to grass or shade if they'll let you.
- Cool the paw with cool (not ice-cold) water for several minutes.
- Don't let them lick the damaged pad — licking makes it worse.
- Call your vet. Burned pads are painful and infection-prone, and anything beyond mild redness needs professional care. Don't apply creams, balms or human burn products to a burn unless your vet tells you to.
A simple summer paw-care routine
The dramatic stuff above is avoidable. The everyday reality of summer is milder but constant: warm pavements, dry air, sand and hard ground all take moisture out of paw pads, leaving them dry, rough and more prone to cracking. A minute a day keeps them right:
- Check paws after warm walks — a five-second look between the toes for redness, grass seeds and grit.
- Rinse after the beach — salt and sand are drying, and grit between the toes rubs.
- Condition the pads regularly. This is where a proper paw balm earns its place. CALM & CARE Paw Balm (£7.00) has been its maker's bestselling paw balm for four years running — massaged into the pads, it keeps them soft and supple, ideal after a day of warm pavements and dry ground. It's handcrafted in Cheshire with natural ingredients like lavender and chamomile, which give it a second string: applied to the paws or behind the ears, it's designed to have a gentle calming effect on anxious dogs too. The maker's tip is to make it an evening ritual — a slow paw massage as the day winds down, which most dogs file under "spa treatment" rather than "maintenance".
What a paw balm won't do (an honesty section)
A balm conditions and soothes pads and helps keep them from drying and cracking. It is not armour: no balm makes a hot pavement safe to walk on, and nothing in a tin replaces the seven-second test. It's the difference between moisturiser and oven gloves — one keeps skin healthy, the other is just not something that exists for paws. Test the ground, walk at the cool ends of the day, and use the balm to keep healthy pads healthy.
The rest of the summer picture
Hot ground is one half of the season's care; the other half happens on picnic blankets. If your dog treats every park picnic as a buffet with lax security, this week's companion guide to probiotics and dog gut health is for you.

Frequently asked questions
How hot is too hot for dog paws?
If the pavement fails the seven-second test — you can't hold the back of your hand flat on it for seven seconds — it's too hot to walk on. Surfaces in direct sun can be 20–30°C hotter than the air, so even a 25°C day can produce tarmac around 50°C.
Can dogs walk on pavement in 25 degree weather?
Often yes in the early morning or late evening, but tarmac in direct sun on a 25°C day can reach temperatures capable of burning pads. Always test the surface first rather than trusting the air temperature.
What time should I walk my dog in a heatwave?
Early morning is safest, before surfaces heat up. Late evening is second best, but test first — tarmac stores heat and can stay hot after the air has cooled.
Does paw balm protect dogs from hot pavements?
No. Paw balm conditions pads, keeping them supple and less prone to drying and cracking — but it does not make hot surfaces safe. Use the seven-second test and walk at cooler times of day.
What do burned dog paws look like?
Redness, darkened or shiny pads, blisters, loose flaps of pad or raw patches — often alongside limping or licking at the feet. Anything beyond mild redness should be seen by a vet.
Are dogs' paws tougher than human feet?
Tougher, yes — but far from burn-proof. Pads are living skin, and surfaces above roughly 50°C can damage them in under a minute.
This guide is general information, not veterinary advice. If you suspect burned pads or heatstroke, contact your vet straight away.
