According to Shawn Messonnier, Holistic veterinarian and founder of Paws & Claws Animal Hospital, Plano, Texas.
Water evaporates quickly and pets tend to drink more in hot weather, so I suggest having several fresh, clean bowlfuls available.
Make sure there's an area of the yard that's shady or protected from direct sunlight and intense heat. Dogs, especially those with light-colored fur (and pale skin), can and do get sunburned, just like people. Apply sunscreen (SPF 30) on the tips of your dog's ears, which are most likely to get burned. You don't need a dog-specific product; it's OK to use a lotion made for humans. If you have a long-haired breed, clip its fur short for the season.
During heat waves, scale back on vigorous walks and exercise, and steer clear of very hot sidewalks, which can burn paw pads. Also be alert for signs of heatstroke, such as excessive panting, drooling, and restlessness. If you notice these symptoms, cool down your dog with cold water and take him to the vet immediately.
It's important to keep up with monthly heartworm-preventive medication in summer, since mosquitoes carry the parasites. And treat the yard for fleas and ticks, which will also be more active. For a pet-safe alternative to harsh insecticides, I recommend applying beneficial nematodes, a staple of organic gardeners, to the soil.
