Glad things went well... but I am on the other side of the fence with the collar issue. One option would be to put a leash on both the harness and the collar, and only use the collar as sparingly as possible.
Another option is to train him to respect his harness and you. This can be accomplished by doing things like figure 8s (teaches him to watch you feet for direction changes), and intentional reverse direction changes when he begins pulling. |
