Constructor's Comments

When I SNAP my fingers, my dog Penny comes running, probably because I've dropped some food on the floor or I'm going to take her for a walk.  That idea was the impetus for this puzzle.  But I was only going to build it if I could find enough in-the-language verbal equivalents of snapping one's fingers.  I think I've done that, and the grid feels pretty lively to me.  As a bonus, I was also able to pull off those stacked long Downs in two of the corners with only a little bit of gunk (ARTE, e.g.).  The finishing touch was the title, which felt like a gift from the crossword gods.  Thank you, crossword gods!
