Heatstroke kills dogs — usually within 15–20 minutes of onset.
If your dog is showing serious signs (collapse, seizures, unresponsive), call your vet now and begin cooling immediately. Do not wait for this page.
Summer Dog Safety.
What Your Vet Wants You to Know.
Hundreds of UK dogs are treated for heatstroke every summer. Many don't make it. This is the complete guide — heatstroke signs, the pavement test, safe walking times, and exactly what to do when it gets hot.

🖐️ The 7-Second Pavement Test
The simplest, most important check before any summer walk.
7 seconds
Press the back of your hand on the pavement.
If you can't hold it there comfortably for the full 7 seconds — neither can your dog's paws.
✅ If you CAN hold it 7 seconds
The pavement is cool enough. Walk time — but still check regularly throughout.
❌ If you CAN'T hold it 7 seconds
Too hot for your dog's paws. Stick to grass. Walk earlier tomorrow.
Why this matters: Asphalt can reach 60°C on a 25°C day — hot enough to cook an egg, and hot enough to cause serious burns on your dog's paws within 60 seconds of contact.
Safe walking times by temperature
The temperature in the shade. Not the "feels like" — the actual air temperature.
Normal walks. No extra precautions needed.
Carry water. Shorter walk in direct sun.
Pavement test mandatory. Stick to shade and grass.
Short walks. Flat-faced breeds: 15 min max. Water always.
Garden sniffing, indoor games, frozen treats. No roads at all.
🐶 Flat-faced breed rule: Bulldogs, French Bulldogs, Pugs, Boxers, and Boston Terriers should use stricter limits — subtract 3–5°C from all the thresholds above. They pant less efficiently and overheat faster. At 25°C, treat them as if it were 30°C.
🌡️ Heatstroke — Signs & What to Do
Know the stages. Heatstroke moves fast — catching it early is the difference between a scary afternoon and a vet bill, or a tragedy.
Stage 1 — Early Warning
Signs to watch for:
- •Panting much harder than usual
- •Excessive drooling
- •Restlessness — seeking shade or cool spots
- •Slowing down, not wanting to walk
- •Licking or chewing paws
What to do:
Stop walking immediately. Move to shade. Offer cool water. Pour cool water on paws and belly. This is your window to stop it escalating.
Stage 2 — Serious
Signs to watch for:
- •Bright red or very pale gums
- •Rapid heartbeat
- •Vomiting or diarrhoea
- •Weakness, stumbling, unable to walk straight
- •Confusion or glazed, unfocused eyes
What to do:
Call your vet immediately. Begin active cooling NOW: cool (not cold) water over neck, armpits, groin. Fan while wet. Drive to vet with windows down.
Stage 3 — Emergency
Signs to watch for:
- •Collapse or inability to stand
- •Loss of consciousness
- •Muscle tremors or seizures
- •No response to your voice or touch
What to do:
999 / emergency vet immediately. Cool with lukewarm water while someone else drives. Do NOT delay — every minute matters.
❌ What NOT to Do — Common Mistakes That Make It Worse
Use ice or ice-cold water
Causes blood vessels near the skin to constrict, trapping heat inside the body. Use cool water — not cold.
Put them in a cold shower or ice bath
Same reason — thermal shock constricts circulation. Cool water and fanning is far more effective.
Wait to see if they improve on their own
Internal organ damage can begin before visible signs. Always call your vet, even if they seem to recover.
Give human sports drinks or Lucozade
Sweeteners and high sodium content can cause additional harm. Fresh cool water only.
Leave them in the car to cool down
A car in sun at 22°C reaches 47°C in 60 minutes. This isn't cooling — it's making it catastrophically worse.
Which breeds are most at risk?
All dogs can get heatstroke. These breeds get there faster.
🐾 Brachycephalic (short-nosed)
HIGHEST RISKPhysically cannot pant efficiently. Overheat at temperatures other breeds handle fine.
🧣 Thick double-coat breeds
HIGH RISKBuilt for cold climates. Their insulating coats trap heat in warm weather.
🐕 Large/heavy breeds
ELEVATED RISKLarger body mass generates more heat and takes longer to cool down.
🦴 Other vulnerable groups
ELEVATED RISKLess able to regulate body temperature or communicate distress as effectively.
10 ways to keep your dog cool this summer
Hot days don't have to be dangerous. They just require a bit of planning.
Walk before 8am or after 7pm
The single most effective thing you can do. Cooler air, cooler pavement, happier dog.
Always carry water
Collapsible bowls cost £2. Your dog needs cool water every 20–30 minutes when it's warm.
Stick to shade and grass
Grass stays 10–15°C cooler than asphalt. Plan routes through parks and green spaces.
Frozen treats
Freeze low-sodium chicken broth in an ice cube tray. Or stuff a Kong and freeze it the night before.
Paddling pool in the garden
Shallow garden paddling pools (£5–10) are one of the best investments for summer dog care.
Cooling mats
Gel cooling mats work well for dogs that will use them. Place in a shaded spot indoors.
Never leave in a parked car
22°C outside = 47°C inside a car in 60 minutes. No exceptions, no 'just a minute'.
Keep the house cool
Close curtains on sun-facing windows during the day. Fans pointing at damp towels are cheap alternatives to AC.
Shorter, more frequent walks
3 x 10-minute shaded walks beats 1 x 30-minute hot walk. Let them sniff — mental stimulation tires them too.
Indoor enrichment
Lick mats, sniff mats, treat puzzles, training sessions. A tired brain is a happy brain on a 30°C day.
Can't walk your dog at safe times?
Most people leave for work before 9am and don't get home until 6pm. That's exactly the dangerous window in summer. This is what professional dog walkers are for.
They walk at 6–8am
Before the heat builds. Cool pavement. Comfortable for your dog. You're already at work.
They check the temperature
A professional walker won't walk your dog in dangerous heat. They'll adapt or reschedule — not guess.
They know shaded routes
Good walkers know which parks, trails, and green spaces stay cool. Not just the nearest street.
You see every step
GPS tracking and photo updates on every walk. You know your dog is safe, walking on grass, in shade.

Frequently asked questions
What temperature is too hot to walk a dog?
Above 20°C you should take precautions. Above 25°C, only walk in early morning (before 8am) or evening (after 7pm). Above 30°C, skip the walk entirely and stick to garden time or indoor enrichment. Brachycephalic breeds (Bulldogs, Pugs, Frenchies) need these limits even stricter — they start struggling at 18°C.
How do I do the 7-second pavement test?
Press the back of your hand firmly on the pavement for 7 seconds. If you can't hold it there comfortably — neither can your dog's paws. Asphalt can reach 60°C on a 25°C day (hot enough to cook an egg). If it's too hot for your hand, it's too hot for their paws.
What are the signs of heatstroke in dogs?
Early signs: excessive panting, heavy drooling, restlessness, seeking shade, slowing down. Serious signs: bright red or pale gums, rapid heartbeat, vomiting, weakness, confusion. Emergency signs: collapse, loss of consciousness, seizures. Call your vet immediately if you see serious or emergency signs.
What should I do if my dog has heatstroke?
Act immediately. Move to shade. Pour cool (not ice cold) water over their body — focus on neck, armpits, groin. Let them drink small amounts of cool water. Fan them while wet. Do NOT use ice — it constricts blood vessels and traps heat inside. Call your vet immediately even if they seem to recover.
Which dog breeds are most at risk from heatstroke?
Highest risk: Bulldogs, French Bulldogs, Pugs, Boxers, Boston Terriers — brachycephalic (short-nosed) breeds that can't pant efficiently. Also high risk: thick-coated breeds (Huskies, Saint Bernards), large breeds (Labs, Goldens), and overweight dogs of any breed.
Can I still walk my dog in summer?
Yes — but time it right. Walk before 8am and after 7pm during hot days. Always carry water. Shorter walks on grass and shaded paths. Watch for early signs (panting, lagging, seeking shade). If you can't walk at safe times due to work, a verified dog walker who walks at early morning and evening hours is the safest solution.
