This is my Blue Heeler "Buster," who can be a great help when I need him. I have a few cows that have figured out when it is time for worming etc....They are supposed to go into a barn lot, then into the holding pen before the chute system. After I try a few rounds of trying to get them in and they run past me, I call Buster ..and for some reason, it jogs their memory where they are supposed to go. I do not like to have to use him. But he does!!
