How PawShade estimates heat and surface risk

Inputs blended into one margin

PawShade combines air temperature, humidity, sun exposure, and surface type with dog-specific modifiers such as brachycephalic risk, age sensitivity, size, water access, and the ambition of the outing. The result is a practical walk margin score rather than a false promise of exact safety.

Surface temperature estimate

The surface estimate starts from ambient temperature, then adds material-specific heat gain and sun exposure penalties. Dark asphalt, dark concrete, and composite decking rise far above grass in direct sun. The estimate is intentionally conservative because real-world surfaces can heat unevenly.

Why the readout can become strict quickly

• Humidity makes panting less efficient.
• Flat-faced, senior, puppy, or medically sensitive dogs lose margin faster.
• Exercise goals demand more cooling capacity than a toilet break.
• No water, no shade plan, and heat-soaked pavement compound each other.

Important limitation

PawShade is not veterinary advice and it cannot see your exact microclimate, pavement color, breeze, or health history. Always verify the actual surface with the 7-second hand test and stop immediately if the dog shows distress.
