Heat is a real emergency risk for dogs
Dogs do not cope with heat the way people do. They sweat very little (only through their paw pads), relying mostly on panting to cool down, which is far less efficient — and flat-faced and heavy-coated breeds struggle even more. On a hot day, a normal walk can quickly become a medical emergency, and heatstroke can be fatal within minutes.
The good news: heat-related illness is almost entirely preventable with a little awareness and planning. The golden rules are simple — keep your dog cool, hydrated, and out of direct heat — and recognise the danger signs early.
The iron rules of summer walks
1: Avoid the hottest time of day
Walk early in the morning or late in the evening when temperatures are low. On very hot days, an overly long mid-afternoon walk is a risk that is easily avoided.
2: Test the pavement
Before you walk, place the back of your hand on the ground for a few seconds. If it is too hot for your hand, it is too hot for your dog's paws — and it can burn them badly. On hot days, choose grass or shady routes instead.
3: Keep it shorter
Hot weather changes how long your dog should exercise. Keep sessions shorter and gentler than usual, and take breaks in the shade.
Hydration and shade every step of the way
- Carry plenty of cold, fresh water and offer it regularly — more than you might think necessary.
- Provide shade wherever your dog rests — indoors and out.
- Never leave a dog in a car, even briefly, even with the windows down. Cars heat up dangerously fast and can kill in minutes.
- Offer water after any heat exposure and watch for excessive panting.
Recognising heatstroke: act fast
Heatstroke needs urgent veterinary care. Know the signs:
- Heavy, fast, or distressed panting that does not ease.
- Drooling or thick saliva, glazed eyes, and a bright-red or pale gum.
- Weakness, staggering, collapse, or vomiting.
If you suspect heatstroke
- Remove the dog from the heat immediately.
- Cool them gently — move to shade, and apply cool (not ice-cold) water to the body, focusing on neck, head, armpits, and groin. Do not use ice: it can constrict blood vessels and trap heat.
- Offer small amounts of water, but do not force it.
- Call your vet immediately — heatstroke is an emergency that requires professional care even if the dog seems to recover.
Extra care for at-risk dogs
- Flat-faced breeds (bulldogs, pugs) and heavy-coated breeds overheat far more easily — the most cautious rules apply.
- Puppies and elderly dogs are more vulnerable and tire faster in heat.
- Overweight or unfit dogs struggle to cool down. Keep heavy exercise out of the heat entirely.
Protecting gifted and dark-coated dogs
Some dogs overheat quicker than others — puppies, seniors, and dark-coated or giant breeds all do. If your dog fits these categories, be the first to shorten walks, offer shade, and skip the hottest hours. Prevention is always easier than treatment.
Common mistakes to avoid
- Leaving a dog in a car "for just a minute". Even on a mildly warm day, a car can become lethal fast.
- Walking in the midday heat. Paw burns and overheating are both risks.
- Waterless and non-shaded outings. Heat without water and shade is a recipe for trouble.
- Ignoring early heatstroke signs or assuming the dog "seems fine".
Recommended gear
- A collapsible, insulated travel water bowl — easy hydration on every outing.
- A cooling mat or cooling coat — active ways to help an at-risk dog stay comfortable.
- A shade umbrella or a well-ventilated rest spot — for those midday breaks.
Frequently asked questions
How hot is too hot to walk my dog? As a general rule, if it is too hot for you to comfortably hold your hand on the pavement, it is too hot for paws. Beyond around 20°C, be cautious and pick cooler times; beyond about 25–26°C, avoid strenuous midday exertion and heat-stress risk, especially for at-risk breeds.
Is it okay to leave my dog outside in summer? Only with reliable shade, constant access to cool, fresh water, and sensible supervision. Avoid leaving a dog outdoors in any period of high heat or direct sun.
Can I shave my dog's coat to cool them? Generally not is the honest answer — a double coat actually insulates against heat, and shaving can increase sunburn and heat risk. Always advise with your vet or a professional groomer before considering it.
When to seek emergency help
If your dog shows any signs of heatstroke — distress-panting, drooling, weakness, collapse, or vomiting — cool them gently and call your vet immediately. Heat illness is time-critical; never wait to see if it "passes", and never hesitate to get your dog professional care.
