As temperatures rise, so do the risks for our canine companions. Heatstroke in dogs is a serious, often fatal condition that every dog owner should know how to prevent. In this guide, we'll walk you through everything you need to know about how to prevent dog heatstroke over the summer, from recognizing warning signs to implementing safe outdoor practices.
Understanding Dog Heatstroke
Heatstroke (also called heat exhaustion) occurs when a dog's body temperature rises above the normal range and it can no longer regulate it. Dogs do not sweat like humans; they rely mostly on panting and minimal sweating through their paws.
Normal dog body temperature: 38.3°C – 39.2°C (101°F – 102.5°F)
Heatstroke begins: Above 40°C (104°F)
Causes of Heatstroke:
-
Being left in a car, even for a few minutes
-
Exercising during hot weather
-
Lack of shade or water
-
Flat-faced (brachycephalic) breeds like Pugs or Bulldogs are more susceptible
🚨 Early Warning Signs to Watch For
Knowing the symptoms is essential in preventing full-blown heatstroke.
-
Heavy panting
-
Bright red tongue or gums
-
Drooling excessively
-
Lethargy or weakness
-
Vomiting or diarrhea
-
Disorientation or stumbling
-
Collapse or seizures
🧊 How to Prevent Dog Heatstroke Over the Summer
1. Avoid Walks During Peak Heat
Only walk your dog early in the morning or later in the evening when the temperature is cooler. Midday walks during hot spells can be dangerous. Take your dogs to places they can swim and access water easily. You can find list of nice places for dogs to swimm in the UK here.
2. Keep Them Hydrated at All Times
Always have fresh, cool water available indoors and outdoors. When you're out, carry a portable dog water bottle or collapsible bowl.
Shop Tip: Check out our hydration travel kits and dog water bottles in the Summer Essentials Collection at Calmshops.co.uk.
3. Never Leave Your Dog in a Hot Car
Even with windows cracked, a parked car can reach lethal temperatures within minutes. Don’t risk it.
4. Use Cooling Mats and Vests
Invest in dog cooling gear such as:
-
Cooling mats
-
Cooling bandanas
-
Reflective vests
These help regulate body temperature during rest or walks.
5. Provide Shade Outdoors
If your dog stays outside, ensure they always have access to natural or artificial shade—trees, umbrellas, or tarpaulins.
Add a kiddie pool with a few inches of water—dogs love to splash and cool down!
6. Groom Appropriately for the Season
While it's tempting to shave a long-haired dog, sometimes their coat acts as insulation. Instead:
-
Brush them regularly to remove dead undercoat
-
Avoid full shaving unless advised by a vet
7. Limit High-Intensity Play
Summer is not the time for long games of fetch or chasing frisbees under the sun. Instead:
-
Play indoors
-
Use automatic ball launchers in shaded areas or early hours
Shop Tip: Our Automatic Ball Launchers are perfect for indoor fun or garden play with minimal overheating risk.
8. Use Cooling Accessories During Walks
Harnesses with cooling gel pads or cooling collars can make walks more tolerable. Wet the collar or vest before your walk for added relief.
What to Do if You Suspect Heatstroke
Act fast and do not wait for symptoms to worsen.
First Aid Steps:
-
Move your dog to a shaded or air-conditioned area.
-
Offer small amounts of cool (not ice-cold) water.
-
Wet towels and apply them to your dog’s neck, armpits, and paws.
-
Use a fan to gently lower their body temperature.
-
Contact a vet immediately—heatstroke is a medical emergency.
Special Tips for Brachycephalic Breeds (Flat-Faced Dogs)
Pugs, French Bulldogs, Boxers, and Shih Tzus are at increased risk due to their compromised airway structure. For them:
-
Skip walks in high heat entirely
-
Keep indoor playtime cool
-
Never use muzzles that restrict panting
