Dog owners advised on heatwave risks: Protect pets from overnight heatstroke

Dog owners are being urged to take extra precautions during hot weather, with experts warning that soaring overnight temperatures can leave pets struggling to cool down while they sleep.

While many people focus on keeping dogs safe during the hottest parts of the day, warm nights can be just as challenging, particularly for breeds with thick coats or those bred for colder climates.

Martin Seeley, sleep expert at MattressNextDay, said: "If you're struggling to sleep during a heatwave, your dog almost certainly is too. Unlike humans, dogs can't cool themselves through sweating and instead rely mainly on panting, making them far more vulnerable to overheating.

"Many owners focus on keeping pets cool during daytime walks, but overnight temperatures can be just as dangerous. Taking a few simple steps before bedtime can help dogs stay comfortable, sleep better and reduce the risk of heat-related illness."

Dogs naturally maintain a body temperature of around 38-39°C, several degrees higher than humans, meaning they can quickly become uncomfortable when temperatures rise. Warm evenings can make it harder for them to regulate their body temperature, especially early in the summer before their coats have fully adapted to seasonal changes.

Signs that a dog may be overheating include excessive panting, drooling, lethargy, vomiting and difficulty settling down to sleep.

To help dogs stay cool overnight during periods of hot weather, Martin recommends the following:

Provide cool sleeping surfaces

Place slightly damp towels or cooling mats in different areas of your home to give your dog a choice of cooler places to rest.

Let them choose where they sleep

Dogs instinctively seek out cooler spots, whether that's a tiled floor, hallway or area with a natural draught. Avoid forcing them to stay in one location.

Keep water within easy reach

Place fresh water bowls in areas where your dog is likely to sleep so they can stay hydrated throughout the night.

Offer a frozen treat before bed

Frozen treats or chew toys can help lower body temperature and provide additional hydration before bedtime.

Groom regularly

Regular brushing removes loose hair and helps your dog's coat regulate temperature more effectively. Avoid shaving most breeds, as their coats help protect them from heat.

Keep evenings calm

Excitement and vigorous play can increase body temperature. Encourage quiet, relaxed activity before bed to help your dog cool down naturally.

Use frozen water bottles

Frozen bottles wrapped in a towel and placed around your dog's bed can help create a cooler sleeping environment overnight.

Martin added: "A dog's fur coat doesn't come off when temperatures hit 30 degrees. If you're reaching for a fan at bedtime, there's a good chance your dog is already feeling the effects of the heat too. A little preparation before bed can make a significant difference to their comfort and wellbeing."
