Penny Goes Running

A Ridgeback loves to run....here's Penny lure coursing, having a ball, when suddenly -.........

....Who is this interloper?? Some sassy Whippet! (Love the expression on Penny's face!)

Ah, well, the run is over and I bet the boss has got some treats for me, 'cuz I did so well! I'll just stare at her until she can't stand it any longer....
