How hot is too hot for dog excercise

What I do before I walk my dog in the summer is try to take her early mornings or late afternoons when the sidewalk isn't too hot. What you do is place the back of your hand on the sidewalk and attempt to hold it there for 15 seconds. If you have to pull your hand off before then, it's too hot for your dog to be walked outside. You wouldn't want their paws to be burnt.

Fur on animals acts as insulation against the heat as well. Your parents sound like the kind of owners that shave their double coated dog in order to "cool them down"

As a general rule, if it is too hot for you, it is too hot for a dog. If you want a quick test, put your palm against the sidewalk. If it hurts you to have it there for more than a few seconds, it is too hot. But that is more of a concern in places this are 90+

If it's too hot for you, it's too hot for the dogs.
Just avoid walking them out at noon.

There's no way in hell 28°C is too hot for dogs if they've their full fur.

Doesn't it only prevent them from getting even warmer when they're in the sun? Something-something the top part is heat up by the sun's warmth but the undercoat stays at the air's temp?

Watch the pavement temperature, and watch the dog. When the tongue gets long, it's time to offer water and possibly a rest.
