Thanx to all for the advice. I realize when I ask a question like this it's hard to answer without knowing what all has been done. I'm also opening myself up to criticism, but hey I'd rather get the advice from people that know what they're doing
I did force to pile, however this dog is pretty sensitive. He takes collar corrections, but can shut down if over done. I may need to re-visit force to pile and adjust for this dog. I also understand about sending him through to back, more than stopping him, I do it 1-1 at most, but should prob change to 3-1 or 4-1.
I don't think he's confused, but I do think it could be related to a confidence issue. Piles are clearly visible, mix of orange and white dummies on a soccer field, same location every morning. Stopping him the whistle, no issues stopping so I haven't felt the need for a collar correction there or a check cord. He does not pop, but he does start out slow and then pick up as he gets closer to the pile.
My initial question was whether I should work on this issue before moving from single T to double T. Based just on the questions, I'm thinking I should revisit FTP, and possibly shorten my back pile (100 yds right now) with white dummies to try to build confidence.
Thanx again for chiming in
