Pet owners across the UK are being urged to take immediate precautions as temperatures could soar to 40°C in some areas during the current heatwave. Experts warn that leaving animals in hot cars or overexerting them outdoors could quickly become life-threatening.
RSPCA calls for temporary 'dog lockdown'
The RSPCA has called for a temporary 'dog lockdown' as red weather warnings are issued across parts of England and Wales. The charity is encouraging owners to keep pets indoors and avoid walks during the hottest period. Lauren Bennet, dog welfare expert at the RSPCA and a former veterinary nurse, said: 'During a red weather warning, dog owners should think of it like a temporary lockdown for their pets. For the next 24-48 hours, routines need to immediately change. This isn't the time for walks, chasing the ball or playing fetch, or exposing pooches to energetic exercise. It's far better for dogs to miss a few walks completely than to suffer the potentially fatal consequences of overheating, or heatstroke.'
Dangers of leaving pets in cars
Pet owners have also been warned that leaving a pet in a parked car can quickly become dangerous. Even on mild days, temperatures inside vehicles can rise rapidly. The RSPCA warns that outside temperatures of just 22°C can rise to a deadly 47°C inside a parked car. This puts animals at risk of heatstroke, dehydration and other serious health complications. Experts say pets should never be left unattended in vehicles, even for a short time.
Recognising heatstroke in pets
Dogs and other animals are especially vulnerable because they cannot regulate their body temperature as effectively as humans. When a pet becomes too hot, they can develop heatstroke, a serious condition that can lead to dehydration, organ failure and, in severe cases, can be fatal. Signs of heatstroke include excessive panting, drooling, lethargy, vomiting, bright red gums, difficulty breathing and unsteady movement. In more serious cases, pets might become confused, collapse or lose consciousness.
If heatstroke is suspected, owners are urged to move pets to a cool area, offer small amounts of water and contact a vet immediately. Owners can help lower body temperature using cool, damp towels or by gently pouring cool water over the body, focusing on armpits, groin, stomach and paws. Avoid ice-cold water or ice packs, as these can restrict blood flow and make cooling more difficult.
Expert advice from Tesco Insurance
Alex Cross, Chief Customer Officer at Tesco Insurance, said: 'Pets can't always show us when they're struggling, which is why it's so important for owners to understand the warning signs that something may be wrong, particularly during warmer weather or after spending time in a hot car. Whether it's heatstroke, dehydration or another heat-related illness, recognising symptoms early and seeking veterinary advice quickly can make a significant difference to a pet's recovery.'
Keeping pets cool during extreme heat
The RSPCA advises owners to keep dogs hydrated and create cool indoor spaces. Their wider guidance includes swapping walks for mental stimulation, using puzzle feeders, improving airflow indoors, and offering multiple sources of fresh water throughout the day. Lauren added: 'These temperatures won't last forever, but the decisions owners make over the next couple of days could have a lasting impact on their pets. For now, the message is simple: pause normal routines, prioritise keeping pets cool and comfortable, and wait until temperatures ease before returning to business as usual.'
