Your dog is panting harder than usual, lying flat on the tiles, and refusing to move — and it's only 10 a.m. Sound familiar? Overheating in dogs can go from uncomfortable to dangerous faster than most owners expect, and the frustrating part is that many of the triggers are completely avoidable. Here are five mistakes that quietly make summer miserable for dogs, plus the straightforward fixes for each one.
1. Walking at the Wrong Time of Day
This is the single most common mistake, and it's an easy one to make. Morning walks that used to be fine in spring can become genuinely risky by July, because pavement absorbs heat overnight and stays warm well into the early hours. The general rule of thumb: if you can't hold the back of your hand on the pavement for five seconds comfortably, it's too hot for your dog's paws — and if it's too hot for their paws, it's too hot for the whole walk.
The fix: Shift walks to before 8 a.m. or after 7 p.m. during a heatwave. It's inconvenient, but it's the single highest-impact change you can make.
2. Assuming Short-Haired Dogs Don't Overheat
Owners of Greyhounds, Boxers, Bulldogs, and Dalmatians sometimes assume their dog's short coat means heat isn't a big concern. It isn't that simple. Coat length is just one factor. Breed anatomy matters enormously — flat-faced (brachycephalic) breeds like Bulldogs and Pugs have restricted airways that make panting, their primary cooling mechanism, far less efficient. A Pug in 28°C heat is working much harder to stay cool than a Siberian Husky at the same temperature.
The fix: Research your specific breed's heat tolerance rather than going by coat length alone. Brachycephalic breeds, elderly dogs, and overweight dogs all need extra precautions regardless of how much fur they have.
3. Giving Cold Water Instead of Cool Water
It feels logical — dog is hot, give ice-cold water. But very cold water can cause some dogs to drink too fast and vomit, which worsens dehydration. It can also cause stomach cramps in dogs that are already heat-stressed. This doesn't mean you should give warm water, just that there's a sweet spot.
The fix: Offer cool (not icy) water frequently throughout the day. If your dog is reluctant to drink, try adding a small splash of low-sodium chicken broth to make it more appealing. Refresh the bowl often — warm, stale water gets ignored.
4. Not Giving Your Dog a Dedicated Cool Spot to Rest
Dogs will seek out the coolest surface they can find — which is why you'll find them pressed against the bathroom tiles or wedged under the coffee table. The problem is that these spots aren't always available, aren't always cool enough, and aren't always where you want your dog to be. Without a reliable cool resting place, dogs often just lie in the heat and slowly build up body temperature through the day.
This is where a purpose-built cooling mat earns its place. The Petananda ChillPad self-cooling pet mat works without electricity or water — it uses a pressure-activated gel that absorbs your dog's body heat and dissipates it, then recharges on its own after a few minutes of non-use. You put it in your dog's usual resting spot, and it does the work passively. It's particularly useful for dogs that sleep indoors but in rooms without air conditioning.
The fix: Give your dog a consistent, designated cool spot. Whether that's a cooling mat, a fan directed at a tiled area, or a shaded outdoor corner with good airflow, the key is that your dog knows where to go and actually uses it. Worth noting: if your home is already well air-conditioned throughout, a cooling mat is a nice-to-have rather than a necessity — your dog is probably fine on any surface.
5. Missing the Early Signs of Heat Stress
Most owners know what heatstroke looks like in its severe form — collapse, glazed eyes, vomiting. But by that point, you've already missed several earlier warning signs that could have let you intervene much sooner.
Early signs of heat stress include:
- Excessive, loud panting that seems out of proportion to activity
- Drooling more than usual, especially thick or stringy saliva
- Seeking cool surfaces obsessively and refusing to move
- Gums that look bright red rather than their normal pink
- Restlessness or agitation followed by sudden lethargy
The fix: Check in on your dog during the hottest part of the day (typically 12–3 p.m.), even if they seem fine. If you notice any of the above signs, move them to a cool area, offer water, and apply cool (not cold) damp towels to their neck, armpits, and groin. If symptoms don't improve within 10 minutes, contact your vet.
Frequently Asked Questions
At what temperature is it too hot to walk a dog?
There's no single universal number because it depends on breed, age, fitness, and humidity. As a practical guide, most vets suggest extra caution above 25°C (77°F), and serious risk above 32°C (90°F) for the majority of dogs. Humidity matters just as much as temperature — a humid 27°C day can be harder on a dog than a dry 30°C day.
Can I use a wet towel instead of a cooling mat?
Yes, a damp towel draped over your dog or laid on the floor works as a short-term measure. The limitation is that it warms up quickly and needs to be re-wetted regularly, which isn't always practical. A self-cooling mat stays at a consistent temperature passively and doesn't leave damp patches on your floor.
Do cooling mats work for cats too?
They do — cats often take a little longer to accept a new surface, but most warm to it (no pun intended) once they discover how it feels. The same principles apply: place it in a spot your cat already gravitates toward, and let them discover it on their own terms rather than placing them on it directly.
Summer doesn't have to be a season your dog just endures. Small adjustments to timing, hydration, and where your dog rests make a real difference. If you want to sort out that cool resting spot without fuss, take a look at the Petananda ChillPad — no setup, no power needed, just a cooler place for your dog to land.
