How to keep a dog cool in hot weather

Dogs can suffer from heat far more quickly than many owners realise. Unlike humans, dogs can’t sweat effectively to cool themselves, relying instead mainly on panting and, to a lesser extent, sweating through their paw pads. This makes them especially vulnerable to overheating during hot weather, particularly breeds with thick coats, flat faces, or those that are older, overweight, or unwell.

While dogs tolerate a wider temperature range than some pets, once temperatures climb above 25°C (77°F) the risk of heat stress increases, and anything over 32°C (90°F) can quickly become dangerous, especially with high humidity or direct sun. Taking a few simple precautions can make all the difference to your dog’s comfort and safety.

Provide Constant Access to Shade

Whether your dog spends time in a kennel, run, or garden, make sure there’s always a shaded spot available throughout the day. Trees, garden structures, or purpose-built shelters work well, but check that the shade actually moves with the sun rather than disappearing by midday.

Keep Fresh Water Available at All Times

Dogs need constant access to cool, clean water in hot weather, and bowls should be checked and topped up regularly since water can warm quickly in direct sun. Adding ice cubes to the water bowl, or providing a few extra bowls around the garden, helps encourage regular drinking.

Avoid Exercise During Peak Heat

Walk your dog early in the morning or later in the evening when temperatures are cooler, and avoid strenuous exercise during the hottest part of the day. Always check pavement temperature with the back of your hand before walking, as hot tarmac can burn a dog’s paw pads within seconds.

Improve Ventilation in Kennels and Shelters

If your dog spends time in an outdoor kennel or dog house, make sure it’s well ventilated with good airflow rather than sealed and stuffy. Position kennels away from direct sunlight, and consider raising them off hot ground to allow air to circulate underneath.

Offer Cooling Aids

Cooling mats, damp towels, or a paddling pool can all help dogs regulate their body temperature during hot spells. Wetting your dog’s paws, ears, and belly with cool (not cold) water can also help bring their temperature down safely without shocking their system.

Never Leave a Dog in a Parked Car

Temperatures inside a parked car can rise dramatically within minutes, even with windows cracked open, and this remains one of the leading causes of fatal heatstroke in dogs. It’s always safest to leave dogs at home rather than risk leaving them in a vehicle during warm weather.

Watch for Signs of Heatstroke

Warning signs include excessive panting, drooling, lethargy, disorientation, vomiting, and collapse. If you notice any of these signs, move your dog to a cool, shaded area immediately, offer small amounts of water, apply cool (not cold) water to their body, and contact a vet straight away, as heatstroke can be fatal if untreated.

With shade, fresh water, sensible exercise timing, and a close eye on the warning signs, most dogs can stay safe and comfortable throughout the summer months. A little extra care during hot spells goes a long way toward protecting your dog’s health.
