Dogs know best. My lab has learned to head to the air conditioned room in the garage rather than the porch with shade. I'm easy, when she wants the AC she gets it....
The low this morning @ 5 am was 77 and high humidity. I opened the back door to let the pups out and it felt like walking into the bathroom after someone took a hot shower.
Yet it was very nice last night after dinner. Wife and I took a nice bike ride around the area and it was VERY pleasant. Yet earlier in the day while I was out working in the garage putting the tachometer on my tractor and doing engine adjustments I was drenched. Looking like I had been soaked by a lawn sprinkler.
