Tough Enough? Old dog says she doesn't want to play, but...!!! 

One of my fave things about Golden Retrievers is how kind they are, even when they insist that they really would like to whoop you (in their special Golden way).
Hazy the Golden spent days trying to get older sissy to play, until finally, this!
My favorite moment is at about 45 seconds in when Nifty (the white/cinnamon Norwegian Buhund} looks at me as if to say, "Daddy, I'm done with this one." And then she attacks.
Well, not much of an attack.
