How to Keep Your Dog Safe in Hot Weather

As the UK experiences increasingly warm summer days, it’s vital that dog owners understand the serious risks that high temperatures pose to their pets. While many of us enjoy the sunshine, dogs are far more sensitive to heat. They are not as efficient at regulating their body temperature and can quickly suffer from heat exhaustion or even life-threatening heatstroke. This guide explains why hot weather is dangerous for dogs, how to recognise the signs of heat distress, and what actions you can take to keep your dog safe, both outdoors and at home.

Why Hot Weather Can Be Dangerous for Dogs

Dogs primarily cool themselves by panting and, to a lesser extent, through the sweat glands in their paw pads. Unlike humans, they cannot rely on widespread sweating to regulate body temperature, which makes them especially vulnerable in hot or humid conditions. Even on days that feel mild to us, a dog can quickly overheat if exposed to direct sunlight, hot surfaces, or enclosed environments.

Some dogs are particularly at risk in the heat. Flat-faced breeds such as Bulldogs and Pugs often struggle to breathe efficiently, making it harder for them to cool down. Puppies, elderly dogs, overweight pets, and breeds with thick or long coats are also more prone to overheating. It’s important to understand that heatstroke can set in even when the temperature outside is only in the low twenties. A conservatory, parked car, or poorly ventilated room can become dangerously hot in minutes.

How to Spot the Signs of Heatstroke in Dogs

Recognising the early signs of heatstroke in dogs can be the difference between life and death. Heavy panting is often the first indicator that your dog is struggling to cope with the temperature. This is usually accompanied by excessive drooling, restlessness, or difficulty settling. As heatstroke progresses, your dog may appear drowsy or confused, may become uncoordinated, or could collapse entirely.

Vomiting and diarrhoea are also common symptoms in heat-stressed dogs. In extreme cases, a dog may lose consciousness or suffer seizures. If you observe any of these signs, you should act immediately. Move your dog to a shaded or cooler area and offer them small amounts of cool—not cold—water to drink. Begin cooling them by pouring room temperature water over their body, particularly around the neck, belly, and paws. Never use ice-cold water or cover them with wet towels, as this can trap heat. Most importantly, contact your vet without delay. Heatstroke is a medical emergency and requires urgent professional attention.

Outdoor Summer Safety for Dogs

Spending time outside with your dog during the summer can still be enjoyable, provided you take sensible precautions. One of the most effective ways to reduce heat risk is to adjust your walking schedule. The best time to walk your dog during hot weather is early in the morning or late in the evening when the ground is cooler and the sun is less intense. During the peak of the day, between 11am and 3pm, it is best to avoid walking altogether. Even short periods of activity in the midday sun can put your dog at serious risk.

Hydration is another essential part of keeping your dog safe outdoors. Always bring fresh water with you and encourage your dog to drink frequently. When planning a day out, choose locations with natural shade or take a sunshade or umbrella to create a rest area. Long exposure to direct sunlight can raise your dog’s body temperature quickly, so providing regular breaks in a cool spot is crucial.

Before heading out, always check the temperature of the ground. Pavements, tarmac, and sand can become extremely hot and can burn your dog’s paws. An easy test is to place your hand on the surface for five seconds—if it’s too hot for your skin, it’s too hot for your dog. Walking on grass or shaded trails is a safer alternative during warm weather.

It is also essential never to leave your dog alone in a parked car. Even on cooler days, the interior temperature of a vehicle can rise to dangerous levels in a matter of minutes. Leaving windows open or parking in the shade does not make it safe. Dogs left in cars are at serious risk of heatstroke and death. If your dog cannot come with you when you reach your destination, it’s safer to leave them at home.

Sunburn is another concern for some dogs, especially those with short or white coats and exposed skin. The ears, nose, and belly are particularly sensitive. Whenever possible, keep your dog out of direct sunlight during the hottest hours. If you have concerns about sunburn, consult your vet about suitable pet-safe sunblock products.

Some dogs enjoy playing in water, and if your dog is confident and calm around it, this can be an excellent way to help them cool off. A shallow paddling pool or a gentle splash in a stream can lower their body temperature and make hot days more bearable. Always supervise water play and avoid overly vigorous activity that might increase your dog’s risk of overheating.

Indoor Cooling Tips for Dogs During Summer

Keeping your dog cool indoors is just as important as managing their comfort outside. Start by maintaining a cool environment at home. Close curtains or blinds on sun-facing windows during the day to block out heat, and use fans to create airflow. For an extra cooling effect, you can place frozen water bottles in front of the fan to chill the air slightly. Make sure your dog can move between rooms freely and settle in the coolest part of the house.

Encouraging your dog to rest on cooler surfaces, such as tiled floors or shaded corners, helps them regulate their body temperature. You can also provide a damp towel for them to lie on, refreshing it with cool water throughout the day. However, it is important not to drape the towel over your dog, as this can trap heat and do more harm than good.

Ensuring your dog stays hydrated is a priority. Place multiple water bowls in different parts of the house and refresh them regularly. If your dog is reluctant to drink, adding a few ice cubes can make the water more appealing. You can also prepare simple frozen treats using dog-safe ingredients like diluted broth to encourage fluid intake and provide a bit of enrichment.

During periods of high heat, it is advisable to reduce your dog’s activity. Replace vigorous play with quieter indoor games such as scent-based challenges, training exercises, or puzzle feeders. These activities keep your dog mentally stimulated without increasing their body temperature.

Regular grooming can also help dogs cope with warm weather. Brushing removes excess fur and allows better air circulation through the coat. If your dog has a heavy or long coat, consider consulting a professional groomer or your vet to discuss whether a trim is appropriate. Never shave your dog without veterinary advice, as this can interfere with their natural insulation and increase the risk of sunburn.

Final Thoughts: Put Your Dog’s Safety First in the Heat

The UK summer may not be tropical, but it can still pose serious risks to your dog’s health and wellbeing. Heatstroke can develop quickly, and by the time symptoms appear, it may already be a medical emergency. That’s why it is crucial to understand the dangers, know the signs, and take proactive steps to prevent your dog from becoming too hot.

Adjusting your routine, offering plenty of shade and water, and avoiding unnecessary exertion during the hottest parts of the day can help keep your dog safe and happy. Above all, trust your instincts. If the weather feels too hot for you, it’s definitely too hot for your dog. With the right precautions, you and your dog can enjoy a safe, relaxing, and fun-filled summer together.
