LifestyleDogsA dog trainer has issued a warning to British owners as temperatures reach 30 degrees in parts of the country - and it's something you should keep in mind all summer long10:15, 26 May 2026Updated 10:16, 26 May 2026Dog owners are being warned about the hidden danger lurking in many gardens this summer as temperatures soar across the UK - and experts say it could make pets seriously ill. With parts of the country expected to hit 30 degrees this week, many Brits will be planning to spend as much time outdoors as possible.‌But according to dog trainer Jack, owners with artificial grass need to be especially careful when letting their pets outside in the heat. In a TikTok warning shared with his followers, Jack explained that artificial turf can become dramatically hotter than natural grass during warm weather - posing a serious risk to dogs lying or walking on it.‌He said: “Artificial grass can be 10 to 20 degrees Celsius hotter than normal turf.” According to the trainer, some artificial grass surfaces have even reached temperatures as high as 93 degrees in testing because the material is essentially made from plastic.‌Jack warned that while dogs may enjoy stretching out on warm artificial grass, owners should consider restricting access during the hottest parts of the day to avoid overheating and burns.The warning comes as Animal Friends Pet Insurance revealed that treatment for sunstroke in dogs cost owners more than £400 on average last year.Experts say certain breeds - including bull breeds, terriers and labradors - are particularly vulnerable during hot weather.‌Dr Webster explained that dogs struggle to regulate their body temperature because they can only sweat through their paws.Instead, they rely on panting to cool themselves down - something that becomes much harder when the air temperature rises.He said: “Their fur coats add to this problem by retaining heat and preventing heat loss.”‌According to the expert, dogs are most at risk of sunstroke when exercising or sitting in direct heat during warmer days.Content cannot be displayed without consentWarning signs include excessive panting, drooling, vomiting, shaking and bright red gums.Article continues belowOwners are urged to act immediately if their pet shows symptoms by moving them into shade and placing cool wet towels over areas including the neck, armpits and hind legs.Dr Webster also warned owners never to use ice on an overheating dog because it can send their body into shock. Instead, pets should be offered water slowly while owners seek veterinary help as quickly as possible.Experts warn that once temperatures hit 24 degrees, sunstroke becomes a real possibility for dogs - while 28 degrees can already become dangerous for all breeds.Choose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌AnimalsDogs
