Hot days and paws

Press the back of your hand flat against the pavement and hold it for seven seconds. If you can't keep it there comfortably, your dog can't walk on it. That's the whole test - it takes seven seconds and it outperforms any temperature rule, because it accounts for surface, color, sun angle and time of day all at once.

Asphalt in direct sun runs dramatically hotter than the air above it - commonly 40-60F hotter. A pleasant 85F afternoon can put dark asphalt well over 130F, which is hot enough to blister pads in under a minute. The air temperature on your phone is not the temperature your dog is standing on.

· Dark asphalt in full sun - the worst by a wide margin
· Metal - truck beds, manhole covers, trailer ramps, boat decks
· Concrete and pavers - hot, but less extreme than asphalt
· Sand and artificial turf - both far hotter than people expect
· Grass and shaded dirt - the safe options

· Limping, or refusing to walk
· Licking or chewing at the feet
· Pads that look darker than usual, or pale
· Visible blisters, missing patches of pad, or redness
· Any of these: stop walking, carry them if you can, and call your vet - burned pads are painful and can get infected

· Walk at dawn or after dark in summer - the surface needs hours to shed heat, so 8pm asphalt can still be too hot
· Route over grass, dirt, and shade; cross streets rather than walking their length
· Boots, if the dog will tolerate them - condition to them indoors first, one paw at a time, with treats
· Paw wax as a partial barrier, not a license for hot surfaces
· Trade the walk for indoor enrichment on brutal days: a snuffle mat and a training session tire a dog out without any pavement at all (see enrichment_toolkit_explained)

Pads are the visible injury; heat is the deadly one. Dogs shed heat mainly by panting, which becomes ineffective in high humidity - so a humid 85F day is more dangerous than a dry 95F one. Flat-faced breeds, seniors, puppies, overweight dogs, and dogs with heart or airway disease have far less margin. Water and shade always, and know the heatstroke signs on your dog's emergency card.

The cold-weather counterpart is de-icing salt, which burns pads and is toxic if licked off - rinse and dry feet after winter walks. See the winter kit in adventure_outfitter.
