One of the great mysteries of the universe...

Why is snow ever so much better than wet grass?

Amos, my darling puppy, is just plain terrified of wet grass.  I find great humor, at times, watching how he tries to stand on just two feet whilst looking about for a place to do his business.  Even funnier is how he will straddle the corner where the sidewalk turns so that he can do his business in the grass but keep all four paws off of it.  He will even take a running start to leap from the sidewalk to the mulch in the flower bed closest to the sidewalk. Of course, as his puppy momma, I also look upon with great sympathy, wishing the experience were not so agonizing for my beloved puppy.

But riddle me this:  how is it that wet grass is the worst thing on the planet while snow is the absolute best?

Amos frolicked about the back yard tonight for nearly an hour before I could get him to come back inside. [I had no desire to run around through the snow to scoop him up.]  He chases imaginary playmates all over the place, leaping and bounding from spot to spot.  He buries his face in the snow and flicks great big clumps in the air and tries to catch them in his mouth.  Truly, not one inch of the back yard is marked by unbroken snow at this point...even though the snow fell just this afternoon  Wagging his tail quite vigorously, Amos takes utter delight in the snow-covered grass.  His joy is rather infectious.

Wet grass is cold.
Snowy grass is even colder and is at least equally wet.
Wouldn't you surmise that a puppy who would do ANYTHING to avoid stepping on wet grass would eschew all contact with snowy grass?

A veritable mystery.
