A few points about keeping your dog cool in the heat. You already know about shade and fans, and that their bare feet burn on hot pavement just like you.

Do try to cool their pads and their fur, but avoid the top of their head. The pads are the most effective area to target with a cool damp towel. The evaporation will help.

If they like water, and you have a tub big enough, a cooling tub of water is great for short periods of time, with breaks. They might also enjoy jumping through a sprinkler (in the shade) or the light spray of a garden hose. Heck, you might join in!

Be careful about ice. Maybe one or two ice cubes in their water, but not more. Drinking very cold water, like ice water, can cause terrible stomach cramps for a dog. And they will need more drinking water than usual.

Tell your dog I said Hi!

@kimlockhartga what are your thoughts on lightweight white cotton t-shirts for dogs that can be soaked with cool water? Especially for dark coated dogs.
@SomeVeganCheeseIsOk We got to the point that we got a summer (nearly shaved) haircut (furcut?) for our pom down here in Heatville, USA. He felt sad without his prideful mane, but he discovered that he wasn't so hot all the time anymore. You do have to watch for sunburn if you do that, though.
@kimlockhartga my dogs are already fairly short haired, so that's less of an option. I also think that one of them would possibly turn into a finger blender if I approached her with intent to shave. She loves me, but she's a neurotic rescue.

@SomeVeganCheeseIsOk I hear you on that.

My little husky mix seems unfazed by any kind of weather.
