Why dogs overheat so fast
Dogs overheat far more easily than people do. They cannot sweat through their skin and must rely on panting, which is inefficient in hot, humid air. Small puppies, flat-faced breeds, elderly dogs, and overweight dogs are at extra risk. Heatstroke can develop in minutes and is an emergency, so prevention is everything.
Know the warning signs
Learn to recognise heatstroke early: heavy, rapid panting, thick drool, bright red gums, glazed eyes, wobbling, vomiting, or collapse. If you see these signs, move your dog to shade immediately, offer small sips of cool, not ice-cold, water, and cool them with tepid water on the belly and paws. Do not wrap them in wet towels, which trap heat. Get to a vet urgently: heatstroke can be fatal even with treatment.
Plan around the heat
Walk early in the morning or late in the evening when it is cooler, and test pavements with the back of your hand: if it is too hot for you to hold for five seconds, it will burn paws. Stick to shady routes, keep walks shorter, and carry water. On very hot days, skip the walk entirely and play gentle indoor games instead. No walk is worth the risk.
Cooling at home
Provide constant access to fresh water, adding ice cubes for fun, and make sure there is always shade and airflow. A damp towel to lie on, a paddling pool in the shade, or a pet cooling mat can help. Never leave a dog in a parked car, not even for a minute with windows cracked: temperatures inside can become lethal terrifyingly fast. Grooming out a thick undercoat, where appropriate for the breed, also helps.
Frozen treats for hot days
Frozen treats are a lovely summer enrichment: freeze low-salt stock, plain yoghurt, or mashed banana with kibble in a food toy. A frozen lick mat can keep a puppy happily occupied during the hottest hours. Watch elderly dogs and puppies especially closely, and remember that excitement raises body temperature, so keep play calm when it is warm.
