He barely sweats. His body dumps heat into whatever he is lying on. The aircon, the fan, the open window: they cool you. They barely touch him. That is why he still pants with the fan on full.

His 38.5°C body heat soaks into any surface until it quits. Vets call it surface heat saturation:

• Gel mats — saturated in 30 minutes (and they leak)
• Frozen towels — body temperature in 10 minutes
• The famous cold tiles — done by mid-afternoon
• Lowering the thermostat — changes nothing on the surface

Mild afternoon panting. Switching spots all day. Sleeping on the bathroom floor. 3 out of 4 indoor dogs show these signs of chronic thermal stress, and owners call it personality.

Ask Beau's owner. Lab mix, seven years old, house at 23°C, fresh water, regular checkups. Three years of 'normal' little signs. Then one ordinary afternoon: heat exhaustion emergency. £3,200.

The FreshPaw mat uses conductive ice silk with a breathable mesh back: it keeps pulling heat away for hours and never turns into a warm patch. Activated by his body weight. No electricity. No gel to leak. No water. No noise. He lies down — that is the whole manual.

24 hours: calmer, slower breathing. 1 week: the afternoon panting stops. 2 weeks: no more bathroom floor, no more drifting room to room.
