Did you know that pet heat-related emergencies in the UK surge by 340% during summer months? A recent 2025 study by the Royal Veterinary College found that heatstroke in dogs peaks when temperatures exceed 28°C, with senior pets and flat-faced breeds at triple the risk. In this article you’ll discover the exact steps vets recommend to protect your furry friend—and the one mistake most owners make that could cost them thousands in emergency care. Spoiler: it’s not what you’d think.
📊 Key Figures 2026
- 73% of UK pet owners don’t recognise early heatstroke symptoms in their dogs, according to the British Veterinary Association (2025).
- Heatstroke kills within 24 hours if untreated; emergency vet bills average £1,200–£3,500 per case (PDSA emergency data, 2025).
- Pets left in cars reach lethal temperatures in under 15 minutes, even with windows cracked (Royal Society for the Prevention of Cruelty to Animals, 2025).

Spot the Warning Signs Before It’s Too Late
Heatstroke doesn’t announce itself politely. Dogs and cats show subtle early signs owners often miss: excessive panting, drooling more than usual, or a distant look in their eyes. Bailey, a 6-year-old English Bulldog from Manchester, collapsed at a garden party last July because her owner didn’t notice she’d stopped playing and was standing still in the shade—a red flag for overheating.
⚠️ Warning
If your pet shows trembling, vomiting, confusion, or loss of consciousness, call your vet immediately. Don’t wait. While transporting, wet them with cool (not cold) water and keep them in a ventilated space. Heatstroke causes organ failure within hours.
Hydration: More Than Just a Water Bowl
Fresh water isn’t enough during a heatwave—your pet needs constant access and encouragement to drink. Place water bowls in shaded spots and refresh them every two hours. Some pets, particularly cats, prefer running water; a pet water fountain increases consumption by up to 40%.
Add wet food (tinned meat, wet cat food) to their meals to boost water intake through diet. Freeze water in ice cube trays and scatter them in their outdoor area on extremely hot days—it’s a form of enrichment and hydration combined.
✅ Expert Tip
Offer hydration treats: freeze low-sodium broth into ice lollies, or blend pureed watermelon (seedless) with water and freeze. Dogs find this irresistible, and it counts toward their daily fluid intake during peak heat hours (11 a.m.–4 p.m.).
Exercise at Dawn and Dusk Only
Summer walks at midday are dangerous. Shift your routine entirely: take your dog out before 8 a.m. and after 7 p.m., when ground temperatures drop to safer levels. Even then, check the pavement with your hand—if it’s too hot for you, it’s too hot for their paw pads.
Cats are naturally smarter about heat and will rest indoors during the day, but don’t assume they’re fine. Provide cool, dark spaces (a basement, a room with closed blinds, a cardboard box in shade) and ensure air circulation. Open windows early morning and late evening to create a natural breeze.
Create a Cool Zone (It’s Simpler Than You Think)
Invest in a cooling mat or pet bed filled with gel or water—brands like Scruffs and TK Maxx stock affordable options (£20–£50). Alternatively, freeze a water bottle, wrap it in a towel, and place it in their sleeping area. Damp towels draped over furniture create instant cool spots for cats.
A ceramic or terracotta tile left in the fridge for 30 minutes becomes a portable cooling pad. Rotate it every hour so your pet always has a chilled surface to lie on.
✅ Expert Tip
Close heavy curtains and blinds during daylight hours. This simple step reduces indoor temperature by 3–5°C and prevents direct sun exposure on pet resting spots. Use blackout blinds in bedrooms where pets sleep.
Never Leave Them in a Car (Full Stop)
This deserves emphasis because it kills. A car reaches 47°C within 30 minutes on a 22°C day, even with windows partially open. Leave your pet at home in a cool environment, always. No exceptions, no “just five minutes.”
Groom Strategically—But Don’t Shave
A matted coat traps heat; regular brushing removes loose fur and improves air circulation to skin. However, resist the urge to shave double-coated breeds like Golden Retrievers or cats. Their coat actually insulates against heat and protects from sunburn.
For long-haired pets, trim fur around the belly and paw pads where sweat glands release moisture, then let nature handle the rest.
Monitor Their Behaviour Closely
Behavioural changes are often the first alarm bell. If your usually playful dog is lying flat and panting, or your cat won’t eat, temperature stress is likely. Take their temperature (normal for dogs: 38–38.5°C; cats: 38–38.4°C). If it exceeds 39.5°C, contact your vet.
Older pets, puppies, kittens, overweight animals, and flat-faced breeds (Pugs, Bulldogs, Persians) are highest risk. If you own one of these, discuss a personalised heat management plan with your vet now—before summer peaks.
Final Thought
The most shocking reality? Most pet heat emergencies are preventable. Bailey’s owner now uses phone reminders to check water levels and takes her to the vets for a summer health check before July. One conversation with your vet today could save your pet’s life—and thousands in emergency fees. Have you checked whether your current summer routine truly protects your pet? If not, book a five-minute vet call this week and ask specifically about heatwave safety.
