The animal welfare charity shares advice for keeping dogs cool in the hot weather10:54, 10 Jul 2026With the third heatwave of the year affecting many areas across the UK, dog owners are remaining vigilant to any signs of heatstroke. As the RSPCA explains, heatstroke can prove fatal to dogs, who can't cool themselves down the same way that humans do.‌The latest advice on the charity's website says: "When a dog gets too hot and can’t lower its temperature by panting, it can develop heatstroke. This can be fatal, so you need to act fast to reduce their body temperature first, then get help." As such, animal lovers should familiarise themselves with the symptoms and act quickly if they spot any worrying signs.‌While some signs of heatstroke are more obvious, such as a dog collapsing or experiencing muscle spasms, others may be harder to spot. For example, the RSPCA said dogs can also experience an increased heart rate, weakness, or noisy breathing.‌Pet owners can also check their dog's mouth for a lesser-known symptom that may appear in the gums. The RSPCA website explains owners should look out for red gums and a red tongue."Whilst this is often a symptom of a dental problem, when coupled with panting and heavy breathing, red gums can occur when a dog is overheating," the charity said. A full list of symptoms can be found on the charity's website.‌The RSPCA website emphasises the importance of keeping dogs cool when it is hot, providing plenty of shade, keeping animals hydrated, and being alert to any signs of heat-related danger. It's advice that owners should pay close attention to this week, owing to high temperatures.In a blog post shared on Wednesday, the Met Office said: "Temperatures are expected to climb into the mid-30s across parts of the UK this week as hot, settled conditions continue, with many areas experiencing their third heatwave of the year."The weather service added: "High pressure remains the dominant feature through the rest of this week, bringing extensive sunshine, dry weather and temperatures widely above 30°C. The hottest conditions are expected on Thursday and Friday, when some locations in England could reach 35 or 36°C."Article continues belowWhile all dogs can get heatstroke, some animals are more vulnerable. The RSPCA said certain breeds, such as flat-faced dogs, could be higher risk.Other factors to consider include age, your pet's coat thickness, and any pre-existing health conditions, especially conditions that affect the respiratory system. Puppies and older dogs might not be able to regulate their temperature as well as other dogs.
