5 second rule for pavement; if you can't keep your hand on the pavement for 5 seconds without the heat being unbearable, do you really think your dog would want to walk on it?
Signs of dogs over-heating;
Excessive panting
Excessive drooling
Lethargic
Weak
Vommiting
Pale or red gums/tongue
Bloody diarrhea
Staggering/falling
And finally unconsciousness
If you think a dog is over-heating, put a small amount of rubbing alcohol on the paw pads. Dogs sweat through their paws, and the rubbing alcohol is a liquid that will evaporate very quickly and should help lower body temperature. Be careful with this method, as too much rubbing alcohol can cause the temperature change to be too much too quick, and could cause shock.
