Today we started on Heel/Autosit and he picked up Heel relatively quickly but did not get Autosit correct until his last workout of the day. I have decided to put him on a prong collar because he has gotten so used to pulling. The prong collar will reduce the number of corrections he needs and will help keep his focus. It doesn't hurt but it puts pressure on his neck that he can feel more easily than a slip chain or a normal leash. It feels different and will put him into a more submissive state.
Reggie is a very sweet little guy. I have enjoyed getting to know him today. Tomorrow we are going to go on a walk in town to practice in a more urban setting. So far, Reggie is doing just fine.
