Dogs shed heat mainly by panting. A Frenchie's short muzzle makes panting far less efficient, so they build up heat quickly — which is why brachycephalic breeds are over-represented in heat-stroke cases, and why our summers need a bit of planning.
Time and place beat everything
- Walk early or late. Dawn and after sunset — skip the midday heat entirely.
- Test the tar. Too hot for the back of your hand for seven seconds, too hot for paws.
- Never a parked car. Not even a minute, not even in shade.
- Shade and water always within reach at home.
Cooling gear that actually helps
The air-mesh harness doubles as an evaporative cooler: dip it in water, wring out the excess, and pop it on. Re-wet it every 20–30 minutes on a hot outing. It only works while damp — once it dries out it can trap warmth instead, so keep topping it up or take it off.
Know the warning signs
Get to cool water and shade — and call your vet — if you see frantic panting, thick drool, bright red or bluish gums, wobbliness, or vomiting. Heat stroke moves fast and is an emergency.
