The UK has been hit by a heatwave. A ballboy at Wimbledon made the news after collapsing in soaring temperatures. Wednesday reached 36.7C and was named the hottest July day on record. \r\n\r\nAs humans slap on the sun cream, animal welfare organisations urge us to protect pets from the scorching weather. At this time of year, dehydration and even fatal heatstroke are very real concerns for animals.\r\n\r\nSally Stevens, director of communications at Wood Green, The Animals Charity, said: \u2018We hear time and again about people who\u2019ve just \u2018popped into the supermarket for half an hour\u2019or run a few errands while leaving a dog inside a car. They can think the animal will be perfectly fine, but in fact, the heat inside a car could be pushing 35 to 40 degrees, even when it\u2019s only half that outside.\u2019\r\n\r\nMs Stevens urged owners to consider their routine more carefully when travelling with a dog, and at the same time called on non-dog-owners to be vigilant of pets shut in vehicles.\r\n\r\nShe added: \u2018I\u2019d also urge everyone out and about over the summer to be conscious of this message and brave enough to report cases of dogs shut in hot cars.\r\n\r\n\u2018By alerting the police, they could help prevent the serious harm to, or death of, an animal.\u2019\r\n\r\nThe PDSA has also encouraged people around the country to keep an eye on pets throughout the warmer weather. In a statement published by the organisation, PDSA senior vet Elaine Pendlebury said: \u201cAlways consider that if you are feeling hot, thirsty and in need of shade, then your four-legged friend is likely to be too.\u201d \r\n\r\nTo view the PDSA's top ten tips for protecting animals during a heatwave click here.
