Heatstroke in Pets: A Risk Even When Resting at Home

Heatstroke in Pets: A Risk Even When Resting at Home Most pet owners associate heatstroke with a dog left inside a hot car or taken for a long walk during the hottest part of the day. However, recent cases reported by European veterinarians show that the risk is not limited to these situations. During periods of extreme summer heat, veterinary clinics have reported treating pets suffering from overheating and breathing difficulties. Some of the affected animals were dogs resting in their gardens, cats travelling in pet carriers, and rabbits and guinea pigs kept in poorly ventilated enclosures. This means that even when we avoid midday walks and never leave our pets inside a car, we still need to actively monitor the temperature and conditions inside our homes. What Is Heatstroke? Heatstroke occurs when an animal’s body can no longer regulate its temperature effectively. It is a medical emergency and a potentially life-threatening condition that can quickly cause damage to internal organs. The sooner cooling begins, the better the chances of a full recovery. Dogs mainly cool themselves by panting. When the air is extremely hot or the room is poorly ventilated, this natural cooling mechanism may not be sufficient. Cats, rabbits, and small rodents can also overheat. Their symptoms may sometimes be more difficult to notice, so unusual panting, severe weakness, or sudden changes in behaviour should always be taken seriously. Which Pets Are Most at Risk? Heatstroke can affect any animal, but some pets are significantly more vulnerable: Flat-faced dogs and cats, such as Pugs, French Bulldogs, English Bulldogs, and Persian cats Pets with thick or long coats Overweight animals Very young or elderly pets Animals with heart, respiratory, or other chronic health conditions Pets that are not accustomed to high temperatures Animals travelling in carriers, cages, or poorly ventilated enclosures Owners of elderly, overweight, flat-faced pets and animals with heart or breathing problems should be especially careful during hot weather. Signs of Heatstroke in Pets Symptoms can develop very quickly. Look out for: Heavy or continuous panting Difficult, rapid, or noisy breathing Excessive drooling Bright red, very pale, or bluish gums Unusual weakness or tiredness Restlessness or confusion Loss of balance or poor coordination A rapid heartbeat Vomiting or diarrhoea Trembling or muscle spasms Collapse, seizures, or loss of consciousness Do not wait for your pet to collapse before taking action. Heatstroke is an emergency, and veterinary care should never be delayed. Panting with an open mouth is not normal in cats and may indicate a serious problem. In rabbits, watch for rapid breathing, hot or reddened ears, weakness, or reduced responsiveness. What Should You Do If You Suspect Heatstroke? 1. Move Your Pet to a Cooler Place Stop all physical activity immediately. Move your pet into the shade, an air-conditioned room, or the coolest area of your home. 2. Begin Cooling Immediately Carefully wet your pet’s body with water that is cooler than its body temperature. For dogs, focus on areas such as the neck, stomach, and inner thighs. Avoid pouring water directly over the head, nose, or mouth, as the animal may accidentally inhale it. When cooling cats, rabbits, or small animals, act gradually and calmly. Sudden soaking may cause additional stress. Use a fan, air conditioning, or open windows when the outside air is cooler to increase airflow and support the cooling process. 3. Offer Water, but Do Not Force Your Pet to Drink Place fresh water nearby and allow your pet to drink voluntarily. Do not pour water directly into your pet’s mouth or force it to drink, particularly if it appears confused, extremely weak, or unconscious. 4. Contact a Veterinarian Immediately Call a veterinary clinic while you are cooling your pet. For dogs, veterinary professionals often recommend the principle of “cool first, transport second”, as every additional minute at a dangerously high body temperature can increase the risk of complications. When travelling to the veterinary clinic, use the vehicle’s air conditioning and continue gentle cooling when possible. What Should You Avoid Doing? Do not cover your pet with a wet towel. A towel placed over the body can trap heat and slow down the cooling process. A damp towel may be placed underneath the animal, but it should not be wrapped around or placed on top of the body. Do not wait for the symptoms to disappear on their own. Even when your pet appears calmer after cooling, internal organ damage may continue to develop. Never leave an overheated pet alone or transport it in a hot, poorly ventilated vehicle. How Can You Protect Your Pet During Hot Weather? Keep at Least One Room Cool Choose a room that is not exposed to direct sunlight. Close blinds or curtains during the hottest hours and use a fan or air conditioning to improve airflow. When the temperature outside is higher than the temperature indoors, keeping the windows closed may help preserve cooler air. Open them later in the day when the outside temperature begins to fall. Provide Water in Several Locations Place multiple bowls of clean, fresh water around your home. This can be especially helpful for cats, elderly animals, and households with more than one pet. Check and refill the bowls regularly throughout the day. Skip Walks During Extreme Heat Walk your dog early in the morning or later in the evening. During extremely hot weather, it may be safer to skip the walk and replace physical exercise with scent games, obedience exercises, puzzle feeders, or interactive toys indoors. Always check the pavement before walking your dog. Place the back of your hand against the surface for several seconds. If it feels too hot for your hand, it is too hot for your dog’s paws. Limit Unnecessary Travel Pet carriers can heat up very quickly, especially when placed in direct sunlight or inside a vehicle without adequate cooling. Postpone unnecessary journeys and appointments when possible, particularly if your pet becomes easily stressed while travelling. Never cover a pet carrier completely, as this may restrict airflow. Check Cages and Outdoor Enclosures Rabbits, guinea pigs, and other small pets should always have access to shade and good ventilation. Remember that the position of the sun changes throughout the day. An enclosure that is shaded in the morning may be exposed to direct sunlight later in the afternoon. Do not place cages directly next to a sunny window or inside a glazed balcony, conservatory, greenhouse, or other space that can heat up rapidly.
