I have watched videos by Evan Graham, Chris Akin, and Hillman. I know Hillman's approach is different so I am mainly asking about the other two. I do like Hillman's approach. But I am trying to distinguish between these methods. If I interpret Graham and Akin correctly in there sequence of collar conditioning I believe they complete here and heal, but not sit until later in the process. Ie. Akin's video on Duck Dog Basics introduces cc to sit near the end of video, well after OB, FF, formal training. Graham goes in to depth on cc's to sit in his Basic Handling right after Casting. Is there a reason behind waiting, or am I interpreting this wrong. Some other posts indicate that people cc'd to sit during OB, I assume meaning they cc'd to sit earlier than when introduced in the two videos mentioned. I understand follow a program, etc. I am just wondering why the difference, what the reason is, or if I am interpreting this wrong. Thanks in advance.
