Quick answer
Goldens often keep working past comfort. Watch heavy panting, dark tongue, drooling, dragging gait, and dull responses—stop activity and cool in shade with water right away. Walk early or late, test pavement with your hand, brush undercoat instead of shaving, and keep cool rest spots indoors.

Tough is not the same as cool

Goldens get labeled hardy—high drive, game for anything. In summer that reputation can delay help. They may not advertise discomfort until they are close to a bad line. The double coat that warms them in winter slows heat dumping, and their eagerness keeps them moving when smaller dogs would quit for shade.

Stop activity on these signs

Panting much harder, tongue long and deepening toward dark red
Dragging or less forward drive on walks
Heavy, watery drool
Vacant stare, slow response to the environment
Gums deep red or pale instead of normal pink

Any one of these: end exercise, move to shade, offer water. Do not wait for collapse.

Safe walk windows

Timing beats raw distance. Early morning and evening are safer; midday pavement can climb past 140°F and burn pads. If the asphalt feels hot on the back of your hand after five seconds, skip the outing. Keep sessions under about 30 minutes in heat, rest in shade once, and prefer grass over blacktop when you can.

Shaving does not cool Goldens

Guard hair reflects some sun; undercoat adds insulation against radiant heat. A full shave can raise overheating and sunburn risk and invite skin trouble. Summer coat care means brushing out dead undercoat so air moves—not clipping to the skin.

Indoors still counts

AC rooms that run warm with poor airflow can still trap heat on a big dog. Give a cool rest zone, fresh water in a large bowl, and change it often. Extra baths are fine if you dry the coat fully—damp undercoat breeds summer skin issues.
