I worked with Brego a bit more, and enjoyed watching his progress.  Little by little he does the seven games better, but it will still be some time to get the kinks worked out.  I enjoy getting him to walk alongside, stop & backup on cue and look forward to the day he will do this on an "invisible rope".  I am learning to give more consistent cues and to release more quickly as soon as he responds, and I know this is important.  It's just hard to observe his actions and remember all the things I should be doing, while trying to manage the rope and stick and use them correctly.  I know I just need practice, but at times it's frustrating.
