By the end of the three-hour training session, Robin had Arnie walking on leash, too. I tried the same routine out for myself that evening and, with a little encouragement, Arnie got up and walked from the house to his crate in the garage and back, with several stops on the way for treats. We did the same thing twice yesterday and again today. He still panics occasionally, but he seems more relaxed each time we do it, so he's getting 2-3 such walks a day for the next week or two.
Arnie has also lost quite a lot of weight. He was a solid cylinder from neck to butt when he arrived and is now developing curves in the right places. Could he have lost 20 pounds in eight weeks?
Keep up the good work, Arnie!
