As the UK heatwave continues with temperatures reaching 29C in London, veterinary experts are warning that certain dog breeds face a heightened risk of heatstroke. Phil Younger, Veterinary Operations Director at Pharmacy2U Pet Health, identified five breeds that require extra caution: Pugs, Bulldogs, Shih Tzus, Border Collies, and Spaniels.
Why Some Breeds Are More Vulnerable
Dogs cannot sweat like humans; they regulate temperature through panting and sweating via their paws. High humidity makes panting less effective, increasing heatstroke risk. Flat-faced breeds such as Pugs, Bulldogs, and Shih Tzus are especially prone due to their brachycephalic anatomy, which impairs airflow. Active breeds like Border Collies and Spaniels may overheat during exercise if not carefully managed.
Phil Younger stated: "Puppies, older dogs, overweight dogs, and those with lighter coats or underlying health conditions are also more susceptible to heat stress." He emphasized recognizing warning signs: excessive panting, heavy drooling, lethargy, vomiting, collapsing, or confusion.
Four Essential Tips for Dog Owners
1. Ensure Constant Access to Fresh Water
Dogs must have cool, fresh water at all times. Add ice cubes to keep water cooler longer, place multiple bowls around the home, and check them regularly. Supervise drinking if using ice cubes to prevent choking.
2. Time Outdoor Activities Carefully
Avoid walks during the hottest parts of the day. Exercise early morning or late evening when temperatures are lower. Carry a travel water bowl for hydration on the go. Never leave a dog in a parked car, as temperatures can rise to lethal levels within minutes.
3. Keep the Home Environment Cool
Use fans or air conditioning to lower indoor temperatures. Provide cooling mats and offer dog-friendly frozen treats or ice cubes made from water or low-sodium broth. Ensure outdoor areas have shaded spots where dogs can escape direct sun.
4. Apply Sun Protection
Dogs with short or thin coats can get sunburned. Use pet-safe sunscreen on sensitive areas like the nose, ears, and belly if they will be outdoors. Check for redness or irritation after sun exposure.
Phil Younger advised: "If you have any concerns, or if your dog shows signs of struggling in the heat, you should always contact your vet for advice."
