Unfortunately, Loki has completely regressed in his acceptance of the harness. He reverted back to being aggressive when we try to put the harness on him. It just goes to show that you cannot use positive reinforcement as a one time training session without follow up. We were using the harness at the rate of once a week. But with each passing week, he was regressing further and further. Then he was at his worst when we were trying to strap him into the car for Chinese New Years. Alas, I will have to begin a new time intensive training session once again.
