Heatwaves and extreme temperatures keep arriving one after another. We haven’t escaped a spell of heat yet, and a break seldom lasts long enough to feel real relief.
People know the basics in this situation. Stay ahead of heat stroke: drink plenty of water, avoid the sun during peak hours, wear light coverings, and seek shade for walks. Yet the question remains: what should be done to protect pets from heat strokes?
The first point to remember is that heatstroke can affect any dog, though brachycephalic breeds are more susceptible. Bulldogs, boxers, and especially pugs often struggle more with breathing when temperatures rise, notes Gloria Matterhorn, who leads the hospitalization service at Puchol Veterinary Hospital. This vulnerability is tied to their shorter snouts and compact airways, which make heat dissipation harder under heat stress.
sweat in animals
Unlike humans, dogs do not sweat through their skin. One of the primary ways they cool themselves is by panting, which increases breathing rate, and through sweat glands located on their paw pads and nose. This system is less efficient than human sweating, so extra care is essential, especially in very hot weather.
Younger dogs, particularly those that are very active, have thick or dark fur, or are overweight, face a higher risk of heat stroke. They heat up faster and have more difficulty cooling down, especially in direct sun or humid heat.
To prevent heat stroke, experts recommend a few practical rules that minimize risk for pets:
Avoid long walks between 12:00 and 16:00 hours.
Outdoor activity is best avoided during extreme heat; it is wiser to schedule walks for early morning or late afternoon. If a walk cannot be postponed, stay in the shade and prevent vigorous exercise, advises the veterinarian.
Always provide them with fresh water
Keep water readily accessible around the house and yard. When you go for a walk or sit on the terrace, carry a bottle or use a drinking fountain to ensure your dog can hydrate frequently. If stopping at a cafe or on a balcony, ensure there is clear access to clean water for your dog.
It is forbidden to leave them locked in the car
The greenhouse effect can escalate inside a vehicle within 15 to 20 minutes, even if the car is left with windows ajar or for only a short time, explains Cerviño. In such conditions, a dog can become overheated very quickly as breathing accelerates and the body temperature climbs, leading to dangerous heat stress if not interrupted promptly.
To assess heat stress in a dog, look for signs such as a rapid, heavy panting that lasts longer than usual, reluctance to move, or a withdrawn posture indicating discomfort. In severe cases, collapse and loss of consciousness can occur, Cerviño notes.
Heatwaves and extreme temperatures continue to follow one another, and the pattern shows little sign of breaking soon. The emphasis remains on practical prevention and swift response to keep companion animals safe through the hottest days.
