7 Vet-Approved Ways to Keep Dogs Cool in UK Summer 2025

Understanding how dogs regulate their body temperature is essential for responsible dog ownership, especially during the warm UK summers we increasingly experience. Dogs mainly cool themselves by panting, which evaporates moisture from their respiratory tract. Their limited sweat glands on paw pads and nose alone cannot sufficiently cope with heat. Breeds such as French Bulldog puppies and Golden Retriever puppies often have increased heat sensitivity, so require special care. This guide shares 7 vet-approved methods to keep your dog cool, hydrated, and safe throughout the 2025 UK summer.

Creating a Safe, Cool Environment for Your Dog

• Provide constant access to fresh, cool water—adding ice cubes can encourage drinking.
• Use cooling aids like pet cooling mats, damp towels, or cooling jackets for safe body temperature reduction.
• Offer shaded, well-ventilated resting areas indoors and outdoors; avoid small enclosed spaces that trap heat.
• Keep a pet first aid kit and your vet contact details handy for emergencies.
• Choose breathable harnesses instead of collars for brachycephalic breeds like French Bulldogs to ease breathing in hot weather.
• Provide indoor enrichment such as scent games or puzzle feeders during peak heat hours to reduce physical exertion.

1. Walk Wisely: Timing and Safety Tips to Prevent Heat Stress

Schedule walks early morning before 8 AM or late evening after 5 PM to avoid peak heat hours from approximately 10 AM to 5 PM. Use the “seven-second pavement rule”: if you cannot comfortably hold your hand on the pavement for seven seconds, it’s too hot for your dog’s paws and can cause burns.

• Take shaded routes or nearby parks with water features to help naturally cool your dog.
• For brachycephalic breeds such as French Bulldogs and Pugs, use breathable harnesses to facilitate easier breathing.
• If temperatures exceed 23°C, consider substituting outdoor exercise with indoor mental activities to avoid overheating.

2. Keep Hydrated: Fresh, Cool Water and Hydrating Treats

Hydration is vital for maintaining healthy temperature regulation. On average, UK dogs require about 50-60ml of water per kilogram of body weight daily; a 20kg dog needs roughly 1 to 1.2 litres. Always ensure fresh, cool water is accessible and replenished frequently indoors and outdoors.

• Carry portable water bowls on walks and offer water regularly, even if the dog isn’t thirsty.
• Ice cubes or vet-approved electrolyte supplements can encourage drinking.
• Hydrating treats like watermelon or cucumber cubes are especially helpful if dogs eat less in the heat.

3. Provide Cool Resting Spots: Shade, Airflow, and Cooling Mats

Create natural shaded areas outdoors using trees, verandas, or shelters. Indoors, fans or air conditioning enhance airflow but do not cool dogs as humans. Avoid confining dogs in sunrooms or enclosed spaces where heat builds up.

• Cooling mats or damp towels provide a cool surface for resting, aiding heat dissipation.
• Lightly mist your dog’s belly and paws with cool water to help regulate temperature—particularly beneficial for thick-coated breeds like Siberian Huskies (Siberian Husky puppies) or Bernese Mountain Dogs (Bernese Mountain Dog puppies).

4. Recognise and Respond to Heatstroke Promptly

Heatstroke is a serious veterinary emergency requiring immediate attention:

• Watch for heavy panting, excessive drooling, pale or red gums, confusion, vomiting, seizure, or collapse.
• If suspected, move your dog to a cooler shaded or air-conditioned area immediately.
• Offer small sips of cool (not ice-cold) water to prevent shock.
• Apply damp towels gently to the chest, belly, and paws to safely lower body temperature.
• Contact your vet urgently for assessment and treatment.

5. Breed and Health Factors Influencing Heat Tolerance

Heat tolerance varies by breed and health:

• Brachycephalic breeds like Shih Tzus, Bulldogs, and Pugs have restricted airways and reduced heat tolerance. They need shorter walks, frequent hydration, and rest in cool areas.
• Double-coated breeds such as Siberian Huskies and Bernese Mountain Dogs require regular grooming and should avoid direct sun and excessive activity in heat.
• Small or thin-coated dogs benefit from pet-safe sunblock on exposed skin and paw protection to prevent burns from hot surfaces.
• Older, overweight, or medically compromised dogs should have their activity further reduced and be closely monitored in warm weather.

Always consult your vet for personalised breed- and health-specific advice to keep your dog safe in summer.

6. Never Leave Dogs in Cars or Confined Hot Spaces

Temperatures inside parked vehicles can rise dangerously fast—even within minutes—posing a serious risk of heatstroke or death. Leaving dogs unattended in cars or small warm spaces is illegal in the UK. Always plan to avoid this risk altogether.

7. Responsible Planning Before Adding a New Dog This Summer

If you’re considering a new dog this summer, research breed heat sensitivity carefully. Use The Kennel Club’s Find a Puppy platform to locate reputable breeders who prioritise ethical practices and guarantee health.

• Avoid impulse buying or acquiring dogs from unregistered sellers who may not ensure welfare in hot weather.
• Discuss your dog’s living environment and summer care with breeders beforehand.

Bonus: Common Questions and Mistakes About Dogs and Heat

Can I Give My Dog Calpol (Paracetamol)?

No. Calpol and other human paracetamol medicines are toxic and potentially fatal to dogs. Always consult your vet before administering any human medication.

What To Do If Your Dog Won't Drink Enough Water

If your dog refuses water, try flavouring it with diluted low-sodium chicken broth or offering ice cubes as treats. Watch for signs of dehydration, including dry gums, lethargy, or weakness, and seek veterinary advice promptly if these symptoms appear.

Understanding How Dogs Moderate Their Temperature in Summer

Quick Answer: Dogs cool down primarily through panting, which evaporates moisture and lowers body heat. Their fur can insulate or trap heat, so shade and hydration are vital, especially for heat-sensitive breeds. Constant access to fresh water, cool resting places, and heatstroke awareness are top vet recommendations for UK summers in 2025.

Vets across the UK emphasise early prevention and breed-specific care to protect your dog’s health during hot weather.

Best Practices for Keeping Dogs Cool in the UK Summer 2025

Key vet-approved tips include walking dogs during the cooler hours of the day, ensuring plenty of fresh water, providing shaded resting spots, grooming appropriately, and monitoring dogs who are at greater heat risk. Never leave dogs unattended in parked cars, and seek urgent veterinary care if heatstroke signs occur.

Common Mistakes to Avoid in Dog Heatstroke Prevention

Avoid walking dogs during peak heat, neglecting hydration, walking on hot surfaces that can burn paws, restricting airflow with collars instead of harnesses on sensitive breeds, and failing to acclimatise dogs gradually to warmer weather. Rapid cooling and immediate vet intervention are lifesaving if heatstroke happens.

Promoting Responsible Dog Ownership for Hot UK Summers

Responsible ownership means understanding canine temperature regulation and providing tailored care—ample water, shade, and exercise adjustments according to breed, age, and health requirements. Always consult your vet and trusted organisations like The Kennel Club’s heatstroke guide for the latest guidance.
