This is definitely a mostly handler-focus drill. That's not to say that you and Koji shouldn't do it...but it shouldn't be all that you do. It's very important that if you work handler focus one day, you should work obstacle focus the next.
ABC is obstacle focus...this is where you can really get some work done. Teach Koji a go. That way if you are standing still, or peeling off, he still goes on.
Dogs aren't born with a natural tendency towards one or the other--they are made this way based on our training. Somewhere along the line you and I rewarded handler focus, or did more handler focus, or somehow encouraged handler focus, and not so much obstacle focus.
I think maybe I'm a little confused as to what your trainer is telling you to do. Maybe I'm not understanding correctly?
I think you got it. It is handler focused. But for the past couple sessions (6-weeks each), I have come to realize we're doing mostly handler focused stuff. Some of it's great (like working on 270's, box work, etc), but some, like this, is where I don't understand why she wants me to pause, when for me, it's not needed. I think for me, she should've seen if Koji would just naturally follow me, and if so, great. Move on. OR, have me send him to jump C while I peel off so he learns obstacle focus. I guess, when I realize I've been questioning why I'm doing certain things, when Koji does it anyways...for the past how many months, I'm just concerned. Does that make sense?
As for us, I'm not sure how you learned....but I think with Greg's system of flatwork, it's very handler focused. Doing circle work and pole turns, it's all about the handler. Oh wait, we did do "obstacle focused" things, but alas, that was when Koji wasn't very toy motivated, so tossing a toy for him to get, he'd go after it, but then turn around half way and come back to me for food. So, even early on, obviously, we didn't find something he liked enough for him to go after.
I wish I knew about these back then. I think it would've worked better than a tossing a bait pouch cuz he saw it as a toy and was like, "eh, whatevers" even though there was food inside it:
Food tubes
But mostly for flatwork, it was watching the handler and doing what they do (turn etc). I recall working on distance, but honestly, not a lot. It was more watch me stuff. Maybe a bit too heavily leaned that way? I also think him being a needy pup didn't help things.
Not sure what motivates Bentley, but now that I have all these great suggestions for dealing with a food motivated dog, I want to try and re-teach a lot of the things he didn't go for when I tossed my bait bag (tossing food didn't always work and I hate tossing it on grass cuz then he gets obsessed with thinking there's food in grass).
I can see all the places I could've done this or that and take a different approach. But since my trainers only kinda new bait bags and tugging, I didn't get a lot of help on "alternatives". Now I have alternatives. I have to see if they'll work.
