Heat, heat, go away

I've been trying to keep Newton busy inside.  His new tricks will soon be revealed once the temperature goes back down to the 80s!  The summer heat waves are terrible especially on Newton's paws.  He doesn't like to 'toilet' on the faux grass we got him and instead does his business on the landscape rock.  Who would've thought that the rocks are cooler to the touch than the grass.  Anyway, visits to the dog park and walks are done early evenings now.  I know he appreciates it.
