Serpentine!

I am teaching my dog Sirius to heel-- which essentially means that he needs to stay on my left side with his front legs even with me and he needs to adjust his gait to my movements-- and Sirius, although very good-natured, is also fast and athletic, so it's easy for him to get ahead on the leash, but I have been reading a lot of dog training books and one of the methods to get your dog to pay attention is to frequently change direction, which is what I have been doing-- I execute a left turn, then a right turn, walk to a tree, walk to another one, walk in a square, walk in a circle, go forward, go backward, etc.-- and I am sure everyone in the park thinks I am a lunatic who likes to torture his dog, especially when I'm executing the "serpentine," but I just channel Peter Falk and Alan Arkin from The In-Laws for inspiration.
