Start with the pavement math, because it’s worse than it feels through shoes: on an 87-degree afternoon, asphalt in direct sun can hit around 143°F — hot enough to burn paw pads in about a minute. The test costs nothing: press the back of your hand to the pavement for seven seconds. Can’t hold it? Neither can they. Grass routes, shaded sides of the street, and dirt trails all stay dramatically cooler than the road.

Then flip the schedule. Summer dog life happens at the edges of the day — the long walk moves to dawn, the patio moves to four o’clock when the shade arrives, and noon becomes nap infrastructure. Water goes everywhere you go, shade gets treated as a feature worth choosing a place for, and flat-faced dogs get the conservative version of all of it, because they overheat before the dogs around them look bothered. The car, ever, is not a waiting room.

Smoke days are the newer summer skill: check the air-quality index the way you check the radar. The EPA’s pet guidance draws the line clearly — once the AQI climbs past the “unhealthy” range, outside is for quick relief breaks, and seniors, puppies, and short-nosed breeds should be inside well before that. When a smoke day lands, don’t fight it; run the indoor-day playbook instead (we wrote one — the nose games are genuinely better than moping).
