Spot the signs
Lethargic, unresponsive behaviour, bloodshot eyes, a red tongue, excessive panting and drooling are all signs that your dog is overheating. Dogs do not sweat through their skin, but only through the pads of their feet. Panting releases heat through the evaporation of moisture (saliva) from their extended tongues.

Which dogs are most at risk?
Most dogs begin to show signs of overheating at temperatures between 81 and 85 degrees but some are more susceptible. The short noses and flat faces of brachycephalic (snub-nosed) breeds like bulldogs, pugs and Pekingese inhibit efficient panting, and thus cooling. Breeds with undercoats, like German shepherds, Pomeranians and huskies are also more prone to overheating. Small dogs overheat quicker than large ones, with older, overweight dogs more at risk.
How to cool your pooch
In the heat, think feet. Cooling your dog’s paws (see above) is always a good starting point. Take them paddling or set up a tub of water they can stand in. If you spray them with water make sure it gets under the belly, between the legs and under the tail (where the major blood vessels are located), not just on their back.
Wrap them up in, or let them lie on wet towels but cool them gradually with cool, not cold, water to avoid causing shock. Some pet shops sell gel-filled cooling mats for indoor cooling without a watery mess.
Never leave dogs alone in parked cars
Not even for a few minutes with the windows open. You might get delayed and car interiors can soar to dangerously high – even fatal – temperatures in minutes. It’s not illegal to leave dogs in parked cars but owners will be prosecuted if an animal is seen to be suffering. When driving, leave windows slightly open or use the air-conditioning.

Walk early or late
In hot weather it’s time to ease back on the exercise, and maybe manage your dog’s exertions by keeping him on a leash. Before 8am and after 5pm are best for walkies; no self-respecting wolf would go out hunting in the mid-day sun.
Hot pavements, road surfaces and sand can seriously burn a dog’s pads. If you can’t hold your palm on a pavement for 15 seconds it’s too hot. Doggie boots can be a pad-saving accessory for city-dwelling mutts in the summertime.
Provide plenty of fresh, clean water
It’s painfully obvious but especially important. Plastic bottles with attached drinking trays, available from pet shops, are great for walks and car journeys. Plop a few ice cubes into the water bowl at home. Freeze low-salt beef or chicken broth in ice-cube trays for a cool treat but give them only a few at a time, as too many can shock the system. In hot weather water and food should be changed regularly.
Give them a trim
Longhaired breeds might benefit from a summer trim but never cut the fur shorter than one inch as this will increase the chances of sunburn. Double coated dogs can have their undercoat thinned.
Bring dogs indoors
Even outside dogs should spend the hottest time of day indoors.
Let them dig
When they are outdoors, provide a shady spot and a space for them to dig. Dogs dig dens to stay cool in.
