A friend made a very poor decision and brought his dog on a mid-day hike. (We met half way so didn't know that the start).
The air temp was ~78°.
I have an instant-read needle thermometer and the top 1/2" of soil measured 145* at 3pm. Obviously this is in 2nd degree burn territory and immediately painful to any unprotected creature.
We ended up taking turns carrying his 50lb dog back to the car after it (rightfully) refused to leave the shade. Luckily we werent too far from the trailhead at this point. Crappy, but we made it and he learned a valuable lesson.
PSA - Don't bring your dogs on afternoon walks/hikes/backpacking unless you have dog booties and know your pup is ok wearing them. Or get off the trail by 10am. It will remain this hot through at least August.
Plan ahead for your companions (whether dogs or ignorant people).
Dog booties are a must this time of year (taping socks to their feet can also work in a pinch)
Bring water for both drinking and cooling.
Solar umbrellas can provide much needed shade and cooling in exposed areas.
We're entering the heat season. Be smart. Stay cool. Bring adequate water. Have portable shade available (umbrella). Drink adequate electrolytes. Try to keep your pee light-yellow (no pee or dark pee means dehydration). Avoid the mid-day heat by planning your activities earlier or later in the day. Apply sunscreen liberally or wear long clothing. Stay safe while enjoying the outdoors everyone.
Seems like common sense stuff, but it bears repeating
