Pure happiness.  Dogs are uncomplicated love and joy.  And in our cynical sad times where tragedy is all over the news 24 hours a day, unconditional love and acceptance are radical ideas, really.  These unorthodogs are here to challenge us all.  To think outside the human-media-internet-profit-margin-calorie-counting-political-mess-box and just go sit in the grass.  Take a walk.  Enjoy a snack.  Stretch out on the sofa.  Let someone smooch your head.  Savor this moment.
