The "7-second rule" for dogs is a simple test to see if pavement is too hot for their paws: press the back of your hand to the ground for seven seconds, and if it's too hot for you to hold comfortably, it's too hot for your dog's paw pads, which can easily burn on surfaces like asphalt, concrete, and even artificial turf. This helps prevent paw burns by prompting you to walk during cooler times (early morning/late evening) or stick to grass, as tarmac can get extremely hot even on moderately warm days.
