As a pet owner, here’s a good rule of thumb to follow: If it’s too hot outside for you, then it’s way too hot for your dog.
Jason Nicholas, veterinarian and chief medical officer at Preventive Vet, says once weather hits 80 degrees Fahrenheit (which seems like Antarctica compared to last week’s 100-plus degree heat wave), pet owners should start taking precautions. Nicholas says he’s seen far too many cases of dogs with heatstroke, a deadly, but completely preventable, condition.
Why can't dogs handle the same weather that humans can? As much as the guy with long blonde hair may look like his similarly-styled Afghan hound, dogs and humans are separate species with much different tolerances to temperature. We have the luxury of being swathed in a massive, perspiring organ that cools us from head to toe. But dogs' thick fur coats make it harder for them to get rid of heat.
Instead of sweating, the main way a dog lowers its body temperature is through panting. These heavy, quick breaths expel heat and cause moisture to evaporate, which cools the blood in the mouth and tongue. However, certain conditions make this technique ineffective. In high humidity, evaporation happens more slowly—which means that even in a nice, shady refuge, no amount of panting will bring down a dog’s internal temperature.

A woman has had a 132-pound (60kg) tumour removed from her abdomen by doctors in the US.
The 38-year-old had been gaining weight at a rate of about 10 pounds a week for two months before she first went to her doctor seeking help.
She was malnourished because part of the ovarian tumour was on her digestive tract and she used a wheelchair because of the weight and the swelling in her legs. It was also on a major blood vessel, prompting fears for her heart.
Dr Vaagn Andikyan assembled the 25 highly-skilled clinical specialists to plan the tumour's removal at Danbury Hospital in Connecticut in February.
He said: "I might expect to see a 25-pound ovarian tumour, but a 132-pound tumour is very rare.
"When I met the patient, she was extremely malnourished because the tumour was sitting on her digestive tract, and she used a wheelchair because of the tumour's weight."
Dr Karl Kulikowski, vice chairman of the hospital's anaesthesia department, said that the team had practised different surgery scenarios to prepare.

Marking another milestone for a changing planet, scientists reported on Wednesday that the Earth reached its highest temperature on record in 2016, trouncing a record set only a year earlier, which beat one set in 2014. It is the first time in the modern era of global warming data that temperatures have blown past the previous record three years in a row.
The findings come two days before the inauguration of an American president who has called global warming a Chinese plot and vowed to roll back his predecessor’s efforts to cut emissions of heat-trapping gases.
In reality, the Earth is heating up, a point long beyond serious scientific dispute, but one becoming more evident as the records keep falling. Temperatures are heading toward levels that many experts believe will pose a profound threat to both the natural world and to human civilization.
In 2015 and 2016, the planetary warming was intensified by the weather pattern known as El Niño, in which the Pacific Ocean released a huge burst of energy and water vapor into the atmosphere. But the bigger factor in setting the records was the long-term trend of rising temperatures, which scientists say is being driven by increasing levels of carbon dioxide and other greenhouse gases.
