As temperatures climb across the Northern Hemisphere, many of us seek refuge from the sweltering heat. But while we can shed layers or jump in a pool, our furry friends are stuck in their “fur coats” all day long. This makes them particularly vulnerable to overheating, as they rely almost entirely on panting to regulate their body temperature—a far less efficient method than human sweating. Unlike us, dogs aren’t adept at self-regulating, often pushing themselves too hard even when it’s dangerously hot.
“Dogs are almost entirely reliant on panting as a way to reduce their body temperature, and that’s a much less efficient way to reduce temperature than sweating,” explains Dr. Victoria Phillips, veterinary surgeon manager at Dogs Trust. “They’re also not very good at self-regulating, so won’t think, ‘Oh, it’s getting a bit hot, I ought to slow down.'”
Thankfully, there are numerous simple yet effective measures we can take to ensure our beloved pooches remain calm, happy, and healthy when the mercury rises.
Smart Strategies to Beat the Heat
1. Adjust Walk Times to Cooler Hours
Just like humans, exercise can quickly lead to overheating in dogs when the sun is at its peak. A recent study revealed that nearly 75% of heat-related illnesses in UK dogs were due to exertion, with 67.5% of those cases resulting from walking alone. This highlights how even moderate exercise can pose a risk.
However, dogs still need regular exercise for a healthy lifestyle. The key is timing. The Kennel Club, the world’s oldest organization of its kind, advises owners to schedule walks for early mornings or late evenings when temperatures are significantly cooler. You’ll likely appreciate the cooler air too!
2. Prioritize Hydration
This simple yet crucial advice applies equally to dogs as it does to people during heatwaves. If you’re heading out with your dog, always carry ample water for both of you. Since dogs can’t drink from bottles like us, remember to bring a portable water bowl for them to lap from.
3. Opt for a Harness Over a Collar
While a collar with identification is a legal requirement in many places, it can be problematic in hot weather. When a leash pulls on a collar, it can press on a dog’s airways, hindering their ability to pant effectively—a vital cooling mechanism.
“At Dogs Trust, we recommend using a harness unless there’s a specific reason that you need to walk your dog using the lead and collar,” Dr. Phillips advises. A well-fitting harness distributes pressure more evenly, allowing for unrestricted breathing and better cooling.
4. Recognize Symptoms of Heat Stress or Stroke
Any dog can suffer from heatstroke, but some breeds and individuals are at higher risk. Flat-faced breeds like Pugs, Bulldogs, and French Bulldogs are particularly susceptible. Puppies, older dogs, those with pre-existing conditions, and especially obese dogs are also more vulnerable.
Dr. Phillips explains, “When a dog is obese, it’s got a bigger body weight, but the body surface area isn’t necessarily that much bigger. So the lung capacity is trying to reduce the body heat for a larger muscle mass, but the lungs are still the same size as if the dog was slimmer.”
Key symptoms of heat stress or stroke to watch for include:
- Heavy panting, even when not exercising
- Breathing problems, especially in flat-faced dogs
- Tiredness or lethargy
- Stiffness or unwillingness to move
- Opening mouth wider than usual
- Excessive drooling and tongue lolling out
- Vomiting
- Diarrhea
- Collapse
- Fitting
Heatstroke is a medical emergency. If you suspect your dog is suffering from it, contact a vet immediately. “I’d call a vet at any of these stages because they can just talk you through it. The latest advice is to call first, transport second,” says Dr. Phillips. While waiting for veterinary guidance, move your dog to a cool spot (ideally air-conditioned) and try to cool them by fanning them or carefully pouring water over their neck, tummy, and inner thighs. Avoid covering them with a wet towel, as this can trap heat.
5. Test Pavement Temperature
We’ve all experienced the scorching heat of pavement on bare feet. Remember, your dog is always “barefoot.” Before walking on paved surfaces, place your hand on the ground. If you can’t comfortably hold it there for five seconds, it’s too hot for your dog’s paws. Stick to grassy areas when possible.
6. Offer a Cooling Paddle
If you have access to a pool or even a dog-specific paddling pool, it can be a fantastic way for your dog to cool down and have fun. Many dogs love splashing around, and a shallow pool offers a safe and enjoyable way to beat the heat.
7. Exercise Caution During Car Journeys
Cars can quickly become ovens in hot weather. Never leave your dog unattended in a hot car, even for a few minutes. If you must travel with your dog, ensure your destination is pet-friendly. Make car journeys more comfortable by bringing cold water in a thermos, taking regular stops, and using window sunshades in the back.
8. Provide Frozen Treats
Just like humans enjoy ice cream on a hot day, dogs can benefit from frozen treats. Instead of human ice cream (which isn’t good for them), try putting ice cubes in their water. Even better, freeze one of their favorite rubber toys for a few hours; an icy chew can be incredibly refreshing during the hottest parts of the day.
9. Use a Damp Towel for Resting
Nighttime temperatures are rising faster than daytime temperatures in many regions, making it harder for bodies to cool down. To help your dog rest comfortably after a hot day, consider placing a damp (not soaking wet) towel on their bed. This can provide a surprisingly effective cooling spot.
10. Consider a Summer Haircut
Beyond looking sharp, a haircut can significantly enhance your dog’s comfort in warm weather, especially for those with long or heavy coats. Your dog’s sweat glands are primarily located in their feet, so keeping the hair on their paws trimmed can help them evaporate sweat more efficiently, thus losing more heat. Groomers also recommend keeping the hair on legs and stomachs extra short to maximize heat loss.
By implementing these simple yet effective tips, you can help ensure your cherished canine companion stays cool, comfortable, and safe throughout the summer months. Their well-being is in our hands, so let’s make sure they have a happy and healthy hot season!
