Record-breaking heatwaves are sweeping across Europe and the US this summer. From London to Lisbon, Berlin to Barcelona, temperatures are soaring past 35°C (95°F) — and for dogs, that's not just uncomfortable. It's dangerous.
Unlike humans, dogs can't sweat through their skin. They rely almost entirely on panting and a small amount of heat release through their paw pads to cool down. When the air is hotter than their body temperature, that system stops working. Heatstroke can set in within minutes — and it can be fatal.
The good news: a few simple changes to your routine and the right cooling gear can make all the difference. Here's what every dog owner needs to know this summer.
🔥 Know the Signs: Heatstroke in Dogs
Before we talk about cooling products, you need to know what danger looks like. Heatstroke is a medical emergency. If you see these signs, act immediately:
- Excessive panting that doesn't slow down with rest
- Drooling — thick, sticky saliva
- Bright red or very pale gums
- Vomiting or diarrhea
- Lethargy, confusion, or collapse
- Body temperature above 40°C (104°F)
If you suspect heatstroke:
- Move your dog to shade or a cool area immediately
- Offer small amounts of cool (not ice-cold) water
- Apply cool water to their paws, belly, and inner thighs — never pour ice water directly over their body, as this can constrict blood vessels and trap heat inside
- Call your vet immediately — even if your dog seems to recover
6 Tips to Keep Your Dog Cool During a Heatwave
1. Walk Early — or Not at All
The pavement test: place the back of your hand on the sidewalk for 5 seconds. If it's too hot for you, it's too hot for your dog's paw pads. During heatwaves, walk before 8 AM or after 9 PM when temperatures drop. On the hottest days, skip the walk entirely and replace it with indoor enrichment — scent games, puzzle toys, or a short training session in the air conditioning.
2. Switch to a Breathable, No-Pull Summer Harness
Most standard harnesses trap heat against your dog's chest — exactly where they need airflow most. A mesh harness changes the game. It allows air to circulate directly through the fabric, keeping your dog cooler during walks without the bulk of a traditional padded harness.
Our pick for summer walks: The AIRE Mesh Harness is built specifically for hot weather. Its full mesh construction means more airflow with every step — covering less of the dog's body while still providing a secure grab handle and front D-ring for no-pull control. If you live somewhere with scorching summers or you walk during daylight hours, this is the harness your dog needs.
3. Upgrade to an Elevated Cooling Bed
Dogs instinctively seek cool surfaces in summer — tile floors, shaded concrete, dirt in the garden. But what about indoors, on carpet or hardwood? A standard plush bed traps body heat and can make overheating worse.
An elevated pet bed lifts your dog off the ground, allowing air to circulate underneath them. It's the closest thing to a personal air conditioner for a napping dog.
Our pick for summer: The OneTigris Elevated Pet Bed has a breathable mesh surface stretched across a sturdy, portable frame. It works indoors and outdoors — set it up in the shade during a BBQ or on the patio while you relax. And when summer ends, it's still a great everyday bed.
4. Carry a Collapsible Bowl for Hydration Anywhere
Dehydration accelerates heatstroke. In hot weather, your dog needs access to fresh water not just at home, but on every walk, car ride, and outdoor adventure. A collapsible bowl takes up almost no space and means you can offer water anywhere — no more pouring from a bottle into your cupped hand.
Our pick for summer: The OneTigris Collapsible Dog Bowl folds flat, clips to a harness or backpack, and keeps water clean from dirt and insects. Take one on every walk — your dog will thank you.
5. Use a Lightweight Collar for Quick Potty Breaks
When it's too hot for a full harness — or you're just stepping out for a two-minute bathroom break — a lightweight collar is more practical. It's less material on the dog's body, which means less trapped heat. Choose one with reflective stitching for evening visibility, since many summer walks shift to dusk.
Our pick for summer: The OneTigris Martingale Dog Collar offers gentle control without choking, and its lightweight design won't overheat your dog during quick outdoor trips. The reflective trim is a bonus for those late-evening walks when the pavement has finally cooled down.
6. Choose a Lightweight Minimalist Harness for Everyday Summer Use
Not every summer walk requires a full tactical setup. For daily use — neighborhood strolls, quick training sessions, errands around town — you want a harness that's light, simple, and low-profile without sacrificing control.
Our pick for summer daily wear: The DIESEL Dog Harness takes a different approach to summer comfort. Instead of mesh, it uses laser-cut craftsmanship to reduce weight while maintaining strength. The result is a sleek, minimalist tactical harness that sits close to the body without trapping heat. It features a top grab handle for quick control, metal D-rings for secure leash attachment, and fully adjustable chest and belly straps for a precise fit. If you want a harness that looks as clean as it functions — and won't weigh your dog down in the heat — this is it.
AIRE vs. DIESEL — which one is right for your dog? Choose the AIRE Mesh if maximum ventilation is your priority — it's the coolest option for scorching days and direct sun. Choose the DIESEL if you prefer a streamlined, minimalist design with laser-cut durability for everyday summer walks, training, and casual outings. Both are built for the heat. The choice comes down to your dog's build and your personal style.

❓ Frequently Asked Questions
How can I cool down my dog fast?
Move them to shade or air conditioning immediately. Offer small amounts of cool (not ice-cold) water. Apply cool, wet towels to their paw pads, belly, and inner thighs — these areas have the most blood vessels close to the skin. Never pour ice water over your dog's entire body — this can cause blood vessels to constrict and actually trap heat inside. If symptoms don't improve within 5 minutes, call your vet.
What temperature is too hot to walk a dog?
There's no single number, but as a general rule: above 25°C (77°F), use caution. Above 30°C (86°F), most dogs should skip walks entirely. Flat-faced breeds (Bulldogs, Pugs, Frenchies), senior dogs, and puppies are at higher risk. Always do the pavement test — if you can't hold the back of your hand on the sidewalk for 5 seconds, it's too hot for paws.
Can dogs get sunburned?
Yes — especially dogs with short, light-colored coats and exposed skin on the nose, ears, and belly. Use a pet-safe sunscreen on these areas. White dogs and hairless breeds are at highest risk. The best protection is keeping your dog in the shade during peak UV hours (11 AM to 3 PM).
How does a mesh harness help in summer?
A mesh harness allows air to flow directly through the fabric, unlike solid nylon or padded harnesses that trap heat against your dog's chest. The AIRE Mesh Harness is built from a breathable mesh material that covers less surface area while still providing secure control. Think of it as replacing a heavy winter jacket with a breathable running shirt — it doesn't actively cool, but it stops heat from building up in the first place.
Is an elevated dog bed really cooler than a regular bed?
Yes — the physics is simple. A regular bed traps body heat in the cushion. An elevated bed allows air to circulate underneath, carrying heat away. The OneTigris Elevated Pet Bed uses a breathable mesh surface and keeps your dog off hot floors, whether indoors or outside in the shade.
How much water does my dog need in hot weather?
A general rule: dogs need 50-60 ml of water per kg of body weight per day under normal conditions. In hot weather, that can double or triple. A 20 kg (44 lb) dog may need 1-2 liters per day in a heatwave. Always carry a collapsible bowl and fresh water on walks — dehydration can set in faster than you think.
