The progress continues. I took Tango to obedience on Tuesday and he was very good, for the most part. His attention was on me (and the string cheese!) for the first 40 minutes or so. We even went into the training room and watched the puppy / beginner class for a few minutes. Or, rather I sat on a chair near the ring and Tango sat next to me and watched me. And didn't bark! I was thrilled. But then it became too much and everything deteriorated. I should have taken him out to the car when I first said I was going to. Oh well. Live and learn.
Tango still fusses and barks when people and dogs come to the shop and doesn't notice the treats that people throw at his head. Maybe I should cut the hair around his eyes?
