As the UK heatwave continues, dog owners are being urged to take immediate precautions to protect their pets from life-threatening heatstroke. Pet experts warn that some dogs can develop severe overheating within minutes if proper measures are not taken. Early signs of heatstroke include excessive panting, thick or sticky drool, red or pale gums, loss of coordination, vomiting, diarrhoea, and collapse. Owners are advised to walk dogs during cooler morning or evening hours, check pavement temperatures, avoid shaving coats completely, never leave dogs in hot cars, and ensure constant access to fresh water.
Brachycephalic Breeds at Highest Risk
Brachycephalic breeds—those with flat faces and short noses—are particularly vulnerable because they cannot cool themselves efficiently through panting. The French Bulldog, or "Frenchie," is a compact, muscular breed with bat-like ears and a flat face. According to Pet MD, "Strenuous activities should be avoided during the hottest parts of the day. Consider cooling mats or fans to help reduce your Frenchie's body temperature, and ensure they have 24/7 access to fresh water."
Boxers are another brachycephalic breed with high energy levels, making them prone to overheating. Owners should avoid walking them during peak daytime temperatures and check pavement heat before walks.
Thick-Coated Breeds Struggle in Heat
The Chow Chow, an ancient Chinese breed with a thick double coat and lion-like mane, was bred for colder climates. Pet MD notes, "When not properly cared for, they can easily overheat." Regular grooming prevents matting and removes excess fur that traps heat. Keeping them indoors during extreme weather is recommended.
The Pekingese, known for its lion-like appearance, also has a long, thick coat and is brachycephalic. Pet MD advises, "Pekingese can't tolerate hot weather… They may benefit from a summer haircut to help them stay cool, and they should always be kept inside during the hottest parts of the day."
Saint Bernards, originally bred for rescue in the snowy Swiss Alps, have thick insulating coats that make them struggle in hot, humid conditions. Avoid shaving their fur and keep them indoors during extreme weather.
Boston Terriers, despite lacking a thick coat, are brachycephalic. Pet MD explains, "Boston Terriers don't have a thick fur coat. But they are brachycephalic, meaning they have a short muzzle that makes it difficult for these dogs to cool themselves off by panting." Schedule walks during cooler hours and check pavement temperatures.
Akitas, large dogs with a thick, weather-resistant double coat, are designed for cold climates. This extra insulation makes them vulnerable to overheating in summer.
General Safety Tips for All Dogs
All dog owners should remain vigilant during the heatwave. Walk pets early or late in the day, test pavement with the back of your hand, provide shade and water, and never leave dogs unattended in vehicles. Recognise early heatstroke signs and act immediately if they appear, as the condition can become fatal within minutes.
