His major tripping stones are with the Heel. He tends to put the brakes on when he gets nervous or confused and so getting him to stick with me in the Heel has been an adventure. This afternoon he did a fantastic job and so I am confident he will do well tomorrow. His Come command is solid and so even if his Heel is not perfect tomorrow I will still be able to give him a little time to run around and enjoy the freedom his new collar will give him and that is always a happy thing.
