If this has been covered before feel free to post a link to a past thread. I have a Seasoned/Senior level dog and need some help. he runs blinds very well. He will take a great initial line and carry for as long as I need him to. He never has no goes, or confidence issues at the line. When I train/hunt/run tests I am always looking for something to improve on. I would really like him to take a cast and hold it as long as he does his initial line out. What I mean by this is if I give him his line and he goes 50-100 yards and starts to drift offline and I give him an angle back, or straight back, he will take the cast and turn to the appropriate side w/o any problem. But he may only take that line for 10-20 yards sometimes before drifting left/right/in/out whatever the direction maybe, it seems random. its not really a bad problem and I can cast him again if I have to. I would just like to know if there is a good drill out there to work on this, or if I just need to continue running cold blinds. Right now I run a few blinds everyday. but I also run a few drills each week, WW or an 8-handed casting drill. When I do this drill I normally put the bumpers about 20 yards out from him, is this a problem? Is this drill teaching him to run only 20 yards and there should be a bumper? Can you run a drill too much? Or should I run the drill and just put the bumpers further out, like 50 yards? Any help, drills, advice would be helpful. thanks.
