As summer heatwaves sweep across many parts of the world, pet owners are being urged to take extra precautions to protect their furry companions. Rising temperatures can pose serious health risks for animals, especially dogs, with cases of heatstroke and burned paws on the rise during the warmer months.

Even on days that don’t feel excessively hot to humans, pets can suffer serious heat-related injuries. According to veterinary experts, late spring and early summer are particularly risky periods, as many dogs are not yet acclimated to the heat and may not be in peak physical condition after a less active winter.

How Heat Affects Pets

Unlike humans, dogs and cats cannot regulate their body temperature efficiently through sweating. Dogs primarily cool down through panting, which works by releasing heat from their airways. However, not all dogs are equally equipped to handle high temperatures.

Breeds with short snouts—such as bulldogs, French bulldogs, and pugs—are especially vulnerable. Their shortened airways make it difficult to pant effectively, drastically increasing their risk of heat-related illnesses. In fact, one study found these breeds are more than four times as likely to suffer from heat illness compared to their longer-snouted counterparts.

On the other hand, some thick-coated breeds, like Samoyeds or huskies, are surprisingly well-adapted. Their double coats, if properly groomed, can actually insulate them against extreme temperatures—although shaving them may do more harm than good.

Obese pets and those on certain medications are also more prone to overheating, making careful monitoring and veterinary advice crucial.

Best Practices for Summer Walks

During hot weather, long or intense walks should be avoided—especially in the middle of the day. Instead, opt for early morning or late evening strolls when temperatures are cooler.

Heat-related risks spike when air temperatures rise above 25°C (77°F), and the danger increases significantly if humidity exceeds 65%. High humidity impairs a dog’s ability to cool down through panting, explains Dr. Ronald Li, a veterinary emergency specialist.

It’s also critical to assess ground temperatures. If you can’t hold your hand on the pavement for 30 seconds, it’s likely too hot for your dog’s paws and could cause painful burns. Stick to shaded paths, grassy areas, or dirt trails whenever possible.

Always carry water for your pet. Offering small sips during your walk helps keep them hydrated and reduces the risk of gulping large amounts at home—something that can lead to bloat, a potentially life-threatening condition.

Never Leave Pets in Cars or Enclosed Spaces

Leaving a pet in a parked car—even for just a few minutes—can be deadly. On a mild 21°C (70°F) day, temperatures inside a car can rise by 11°C (20°F) within 10 minutes. The same applies to greenhouses, sunrooms, and mobile homes. Even stray cats can fall victim, sometimes becoming trapped in overheated sheds.

Always check enclosed spaces before locking them, and never leave animals unattended in areas prone to trapping heat.

Useful Gear and Grooming Tips

If walking on hot pavement is unavoidable, consider dog booties to protect your pet’s paws. Just be sure they fit properly to prevent sores or abrasions.

Cooling vests, marketed by some pet supply brands, can provide short-term relief—particularly during brief periods of physical activity. However, their cooling effect is often temporary and may diminish after 10 minutes as the material warms up.

Some pets with light-colored noses or thin coats can benefit from a layer of baby-safe sunscreen to prevent sunburn. Cats, in particular, are at risk of skin cancer on exposed areas like the tips of their ears and noses.

Regular brushing helps remove excess fur and promotes better airflow through your pet’s coat. Always consult your veterinarian before shaving your pet, as improper grooming can do more harm than good.

Warning Signs of Overheating

Pet owners should learn to recognize the early symptoms of overheating. In dogs, the most common sign is heavy panting—especially if it becomes loud or labored. Cats may start breathing through their mouths, which is an unusual behavior and a red flag.

If your pet’s body temperature rises above 41°C (105.8°F), they may become disoriented or weak. In dogs, gum color can shift from pink to a bright red, indicating heatstroke. If you observe any of these signs, seek veterinary help immediately.

If you cannot reach a clinic within 10 to 15 minutes, begin cooling your pet at home using cool—not ice-cold—water. A bath or gentle shower followed by a fan can help lower their body temperature. Avoid using icy water, as it can constrict blood vessels and slow the cooling process.

Stay Vigilant and Prepared

Heatstroke is a medical emergency that can cause kidney damage, internal bleeding, or even death if left untreated. During periods of extreme heat, it’s crucial for pet owners to stay alert, limit outdoor activity, and provide ample shade and water.
