Most dogs will go for a walk anytime — even if it’s pouring rain, they want to get out there and check it out. But that doesn’t mean you should always take them for a walk — especially in the summer.

A dog-training center in Sonoma, Calif. posted a tip on Facebook earlier this month, to see if it’s too hot to walk your dog. Now it’s going viral.

It says to feel the pavement with the back of your hand, and if you can’t leave it there for five seconds, your dog should stay inside. If it’s too hot for the back of your hand, it’ll burn their feet.

If that’s the case, either walk them somewhere where there’s grass, or at night. You could also get little boots for them, but most dogs hate wearing them.

Speaking of things dog’s hate, you also might want to leave them at home for the Fourth of July, since fireworks tend to freak them out.
