2013, Day 206 - Freight train

This is Frankie's brother Sand lure coursing.  Although they're both handsome Sand is a really solid boy, he is about the same height but literally twice Frankie's width.  He is a freight train; Sand builds momentum quickly and there is absolutely no stopping him.  This boy LOVES to run and even though he has more weight to move than most dogs his size he has so much heart, so much drive, that they can't keep up.  Here he's barking at the lure to let it know who's boss!
