Which Way???

When i ride my pony Pippi down the rode, my dog Angel follows me. She is a young black kelpie. Angel isn't a real sheep dog, she is a chook dog. Angel is always in front and when we get to the bottom of the drive, she doesnt know which way. If we going to go right she goes left. If we're going left she goes right. Angel does not know whick way to go. Its like she is playing a trick on me.
