Update

I backed off the treat and praise reduction plan a bit since it seems to be stressful for Wyatt. At run thrus last week, the lack of treats and reduced communication did not seem to affect him. Perhaps, he now knows and contextualized the fact that treats come later when we are at an agility/obedience trial but not at home. We had a good run thru. His drop was slow so I gave a second command but it turned out he was dropping so I should have just waited. Sits were difficult for both dogs today but Wyatt has been good at home. I do need to proof the sits more at home and away from home.
