Team training tonight! S ran for Z - I love working with S because she's got some great insights and suggestions and doesn't talk to me like a complete dog training novice like D often does.
We decided to do 2 runaways and then a short trail at the end. Both runaways were about 50 ft in length and Z did ok - she did have some trouble returnign to me quickly on the second one, but her initial sprint to S's hiding spot was nice on both - good motivation and on task.
For the track at the end, S ran about 100 ft straight away and then turned a sharp left and went into the woods about 60 ft. Z was really revved up while we waited for S to signal that she was in position and she took the scent article nicely, too. Upon release she sprinted along S's track but blew right by the turn. She got a hard negative after about 15 ft or so, looped back and S said she appeared on track for about 10 ft before veering off to the side. I didn't have to call her off of this detour (yay!), and once she came back she got back to work nicely and found S without any cuing from either of us. Her refind was a bit slow, but ok.
S believes Z was crittering on the detour, but I'm not so sure. Even if she was, I'm happy because she disengaged on her own which is a new thing for her; up 'til now she's always either been on task completely or had to be called off the critter distractions. Still more work to do, but I think we're moving in the right direction at least.
