We all love it when a British summer finally comes around. But as the temperatures soar in and the Met Office starts issuing heat warnings, our thoughts immediately turn to our four-legged best friends. UK homes are notoriously well-insulated to keep heat in, which means when a summer heatwave hits, our houses can quickly turn into greenhouses.
If you are wondering how to keep your dog cool during hot weather, you aren't alone. Balancing their need for exercise with summer safety can be tricky.
Here is your ‘all you need to know’ evidence-backed guide to keeping your pup safe, happy, and chilled when the UK heats up.
1. Timing the Walks: When is it Too Hot?
One of the most frequent questions pet parents ask in summer:
when is it too hot to walk a dog?
As a general rule, once the ambient temperature hits 20°C, you need to proceed with caution. If it pushes past 24°C, traditional midday walks should be completely off the table. Instead, restrict exercise to the early mornings or late evenings when the air has cooled down.
Before you step out the door, always perform the 5 second tarmac test dogs rely on to protect their paws. Place the back of your hand firmly on the pavement. If you cannot comfortably hold it there for five seconds, the ground is far too hot for your dog's sensitive paw pads and can cause severe burns. If in doubt, stick to shady grass or opt for indoor mental stimulation games instead.
While some countries routinely handle temperatures above 30°C, the UK faces unique challenges because our infrastructure and dogs are not fully acclimatised to sudden, intense heat spikes. This vulnerability is highlighted by the British Veterinary Association, which reported that 38% of vets have treated dogs for heatstroke following walks on hot days.
If your dog demands a walk, rather than adopting a blanket "don't walk" policy, the key is to "walk differently" by adjusting your approach based on the thermometer:
- Above 24°C, avoid intense exercise and carry water;
- Above 26°C, limit outings to early morning or late evening toilet breaks on grass;
- And above 28°C, keep outdoor time exceptionally brief, especially for flat-faced, elderly, overweight, thick-coated, or unwell dogs.
2. Myth-Busting: Can You Put a Wet Towel Over a Dog?
When looking for a quick fix to cool a panting pup, many owners turn to the internet and ask: can you put a wet towel over a dog?
The short answer is no. While it seems intuitive, draping a damp, heavy towel over your dog's back actually creates a dome effect. It traps the heat escaping from their body against their skin, warming them up rather than cooling them down.
Instead, lay a damp towel on the floor for them to lie on if they choose to, or better yet, invest in purpose-built cooling gear such as non-toxic cooling mats or cooling vests.
3. Invest in the Right Summer Cooling Gear
Modern pet technology has made keeping your dog comfortable much easier. If you want to prepare your home for the next heatwave, look into these summer essentials:
- The Indoor Chilling Station: A high-quality, non-toxic dog cooling mat UK pet owners trust is the easiest way to give your dog instant relief. While pressure-activated gel options are popular, they come with a major safety warning for destructive pups: cheaper imports can be toxic, and swallowed pieces can cause dangerous stomach blockages. If your dog loves to chew, bypass gel entirely and opt for an ice silk pet cooling mat. These use breathable, advanced cooling fabrics with absolutely zero gels, chemicals, or liquids inside—making them a 100% chew-safe, naturally cool-to-the-touch alternative.

The Quick-Cool Accessory: For an easy, everyday solution that doesn’t restrict movement, a dog cooling scarf (or dog cooling bandana) is an absolute must-have. Because a dog's major blood vessels sit very close to the skin around their neck, cooling this specific area helps lower their core body temperature quickly and efficiently. Depending on your dog's lifestyle, there are two brilliant styles to choose from:
- The 'Soak and Activate' Mesh Scarf: Made from advanced lightweight, technical fabrics, you simply submerge this scarf in cold water, wring it out, and snap it to activate. It uses evaporative technology to keep the neck area chilled without feeling soaking wet against your dog’s fur, making it perfect for quick outdoor toilet breaks.
- The Ice-Pack Pocket Scarf: Ideal for intense heatwaves or uninsulated indoor spaces, this design features a secure, built-in pocket specifically tailored to hold a mini, reusable gel ice pack. You simply freeze the small cooling pack ahead of time, slip it into the insulated pouch, and fasten the scarf. This provides a direct, long-lasting ice-cool barrier that keeps your dog comfortable for hours at home.
- On-the-Go Protection: If you do have to travel or take a short morning stroll, a specialised dog cooling vest is highly effective. These cooling vests work via evaporative cooling. You soak the vest in cold water, wring it out, and as the water evaporates into the air, it mimics the cooling effect of sweating. You can even put the damp vest in the fridge for extra cooling sensation if the outdoor heat is bad.
- Garden Playtime: If you want to keep outdoor activities safe and engaging, investing in a robust dog paddling pool is recommended. Unlike flimsy plastic children's pools that could easily puncture, a specialised dog pool is designed to withstand sharp nails during the splash. For ultimate protection, pair their water playtime with a cooling vest. This lightweight layer acts as a physical sunblock to shield sensitive skin from UV rays, while providing extended evaporative cooling as your dog happily dashes around the garden in between dips.
4. Hydration and Frozen Enrichment
Keeping your dog hydrated is vital, but drinking plain water can get boring. Why not make it a game?
Using a dog ice lolly maker or silicone freezing moulds allows you to create healthy, low-calorie frozen dog treats UK pups will obsess over. You can freeze low-salt dog safe bone broth, blended dog-safe fruits (like blueberries and bananas), or a bit of water mixed with their favourite wet food. Add a chew snack stick in the lolly to give your dog a grip so they can really work into it!
How to Keep Dogs Cool at Night
Because UK bedrooms rarely have air conditioning, figuring out how to keep dogs cool at night during a UK heatwave can be a nightmare. Keep a circulating fan running in the room (ensuring the cord is safely out of reach), leave your dog's bedroom door open so they can seek out cooler tiled floors, and place their cooling mat right next to their bed.
5. Know the Signs of Heatstroke
Even with the best preparation, heat stress can happen. It is vital that every pet owner can recognise the early signs of heatstroke in dogs before it becomes a medical emergency.
Be on the high alert for:
- Heavy, frantic panting
- Bright red or dark gums and tongue
- Excessive drooling or thick saliva
- Lethargy, weakness, or stumbling
- Vomiting or diarrhoea
If you are researching how to keep a French Bulldog cool in a heatwave—or any other flat-faced (brachycephalic) breed like Pugs and English Bulldogs—you need to be doubly vigilant. Because of their shortened airways, these breeds cannot cool themselves down efficiently through panting and are at a significantly higher risk of heat stroke at much lower temperatures.
If you suspect your dog is overheating, move them to a cool, shaded area immediately, pour cool (not freezing) water over their body, position a fan near them, and call your vet right away.
Summary: A Simple Checklist for Hot Weather
By making a few small adjustments to your daily routine, you can ensure your dog stays safe and comfortable all summer long. Keep walks early, ditch the wet towels, keep the frozen treats flowing, and ensure they have a dedicated cooling mat in the shade to retreat to when the British sunshine gets a bit too intense.
