 Back to hot Las Vegas. If you've got a dog at home, here is something to think about. If it's too hot for people, it is definitely too hot for pets. So consider walking late at night or perhaps early in the morning like this when it's in the mid 80s. And you can check and see if it's safe to walk on by kind of touching the back of your hand to the ground. And if it feels OK, it's good for your dog.
