When a heatwave arrives, it's natural to want to get outside and enjoy the sunshine. But while warm weather can be lovely for us, it can quickly become dangerous for our dogs.
Unlike humans, dogs can't cool themselves down efficiently through sweating. They mainly regulate their body temperature by panting, which means they can overheat much faster during hot weather. Even a routine walk can become risky if temperatures soar.
The good news is that your dog doesn't have to miss out on exercise altogether. By adapting your routine and choosing cooler activities, you can keep them active while protecting their health.
Why Heatwaves Are Dangerous for Dogs
Dogs are far more vulnerable to heat-related illnesses than people. High temperatures, combined with humidity and direct sunlight, can quickly lead to dehydration or heatstroke.
Some dogs are at even greater risk, including:
- Puppies
- Senior dogs
- Overweight dogs
- Flat-faced (brachycephalic) breeds, such as Bulldogs, Pugs and French Bulldogs
- Dogs with heart or breathing conditions
- Thick-coated breeds
Knowing your dog's limits is key to keeping them safe.
Walk Early or Late
The simplest way to reduce the risk of overheating is to avoid exercising during the hottest part of the day.
Instead, aim for:
- Early morning walks before the sun is high
- Evening walks after temperatures have dropped
- Shady woodland or park routes where possible
Not only will your dog stay cooler, but you'll avoid scorching pavements and uncomfortable conditions.
Check the Ground Temperature
Pavements, sand, artificial grass and decking can become much hotter than the air temperature.
Before heading out, do the five-second test:
Place the back of your hand on the pavement for five seconds.
If it's too hot for your hand, it's too hot for your dog's paws.
If the ground feels hot, choose grassy areas instead or postpone your walk until it's cooler.
Shorter Walks Are Better
During a heatwave, your dog doesn't need their usual long walk.
Instead, opt for:
- Two or three shorter outings
- Gentle strolls rather than energetic hikes
- Plenty of sniffing opportunities, which provide excellent mental stimulation
Remember, dogs often get just as much enjoyment from exploring new scents as they do from covering long distances.
Always Carry Water
Hydration is essential.
Whenever you're out with your dog, pack:
- Fresh drinking water
- A portable water bottle
- A collapsible travel bowl
Offer regular drinks, even if your dog doesn't seem thirsty.
Never rely on finding water along your route, especially during very hot weather.
Swap Physical Exercise for Mental Enrichment
If it's simply too hot outside, skip the walk altogether.
Instead, keep your dog entertained indoors with activities such as:
- Puzzle feeders
- Snuffle mats
- Training sessions
- Hide-and-seek games
- Frozen enrichment toys
- Scent games around the house
Mental exercise can be just as tiring as physical activity and helps prevent boredom.
Enjoy Water Safely
Many dogs love cooling off in water during the summer.
If your dog enjoys swimming:
- Choose safe, clean locations
- Avoid fast-flowing rivers
- Watch out for blue-green algae
- Supervise them at all times
- Rinse off saltwater after beach visits
Never force a dog into the water if they're uncomfortable.
Know the Signs of Heatstroke
Heatstroke is a medical emergency and requires immediate action.
Watch out for:
- Excessive panting
- Thick drool
- Bright red gums or tongue
- Weakness
- Vomiting
- Confusion
- Collapse
If you suspect heatstroke:
- Move your dog into the shade immediately.
- Offer cool (not ice-cold) drinking water.
- Gradually cool them with cool water.
- Contact your vet straight away.
Prompt treatment can make a significant difference.
Keep Your Dog Comfortable After Exercise
Even after a short walk, dogs need time to cool down properly.
Create a cool, quiet space indoors where they can relax away from direct sunlight. Closing curtains during the hottest part of the day, improving airflow and ensuring they always have fresh water available can all help them recover comfortably.
A supportive dog bed with a removable, machine-washable cover provides the perfect place for your dog to stretch out and rest after their adventures. It's also practical for summer, making it easy to freshen up after sandy paws, muddy walks or cooling off in the garden.
Don't Forget Your Garden
If your dog spends time outside at home:
- Make sure there's plenty of shade
- Keep water bowls topped up
- Avoid encouraging energetic games in the midday heat
- Consider using a paddling pool if your dog enjoys water
- Bring them indoors if temperatures become excessive
Remember, artificial grass and patios can become extremely hot in direct sunlight.
Frequently Asked Questions
Is it safe to walk my dog during a heatwave?
Yes, but only during the coolest parts of the day. Early mornings and late evenings are usually the safest times. If temperatures remain very high, it's often better to skip the walk and provide indoor enrichment instead.
What temperature is too hot to exercise a dog?
There's no single temperature that's safe for every dog, as factors such as humidity, breed, age and fitness all play a role. As a general guide, once temperatures reach around 20°C, take extra care, and when they climb above 25°C, it's usually best to avoid daytime exercise.
How can I tire my dog out without walking them?
Puzzle toys, scent games, short training sessions, frozen treats and interactive play can all provide valuable mental stimulation that helps tire your dog without risking overheating.
Can I take my dog running during a heatwave?
It's generally best to avoid running with your dog during very hot weather. High-intensity exercise greatly increases the risk of heat exhaustion and heatstroke.
Final Thoughts
When temperatures rise, your dog's safety should always come before sticking to their usual exercise routine. A shorter walk at the right time of day, plenty of water, and engaging indoor activities can help keep them happy and healthy until cooler weather returns.
By recognising the signs of overheating, avoiding the hottest parts of the day and providing a cool, comfortable place to rest, you can ensure your dog enjoys the summer safely. Sometimes, the best decision you can make is to swap a long walk for a quiet game indoors and an afternoon snooze.
