As the UK heatwave continues with temperatures reaching 29°C in London, veterinary expert Phil Younger warns that three dog breeds are particularly at risk: Pugs, Bulldogs, and Shih Tzus. These flat-faced breeds struggle to cool down through panting, making them more susceptible to heatstroke.
Why Dogs Struggle in the Heat
Phil Younger, Veterinary Operations Director at Pharmacy2U Pet Health, explains: "Dogs do not sweat like humans. Instead, they regulate their body temperature by panting and sweating through their paws. However, when temperatures are high, particularly during periods of high humidity, panting becomes less effective, making it much harder for dogs to cool themselves down. This significantly increases the risk of heatstroke."
Warning signs of overheating include excessive panting, heavy drooling, lethargy, vomiting, collapsing, or confusion.
Breeds Most at Risk
Flat-faced breeds such as Pugs, Bulldogs, and Shih Tzus are especially vulnerable due to their brachycephalic anatomy. Active breeds like Border Collies and Spaniels also require extra care. Younger adds: "Puppies, older dogs, overweight dogs, and those with lighter coats or underlying health conditions are also more susceptible to heat stress."
Four Tips to Keep Dogs Safe
1. Provide Plenty of Fresh Water
Always ensure access to cool, fresh water. Add ice cubes to keep it cooler longer, place multiple bowls around the home, and check them regularly. Supervise drinking if using ice cubes to prevent choking.
2. Limit Outdoor Activities
Avoid walks during the hottest parts of the day; early mornings and late evenings are safest. Carry a travel water bowl and never leave a dog in a parked car, as temperatures can rise rapidly to life-threatening levels.
3. Create a Cool Environment at Home
Keep the home well ventilated with fans or air conditioning. Use cooling mats and offer dog-friendly frozen treats or ice cubes made from water or low-sodium broth. Ensure outdoor shaded areas are available.
4. Protect Your Dog from the Sun
Apply pet-safe sunscreen to sensitive areas like the nose, ears, and belly. Dogs with short or thin coats are vulnerable to sunburn. Check for redness or irritation after sun exposure.
Younger advises: "If you have any concerns, or if your dog shows signs of struggling in the heat, you should always contact your vet for advice."
