The handler tries to keep the dog on line while it goes over the log, across the ditch, away from the poison bird, past the tree and picks up the bird for which it was sent. Overcoming these various factors are taught and trained abilities. That are learned through a complete, thoughtfull, detailed step by step program. This kind of program approach is required to be successful even at the Senior level.
There is a lot more to a competition dog than a simple basic gun dog, so you need to select training programs and methods that will get you to where you want to be.
So would that be: Whistle after log, dog is drifting to left of line.
Then left back cast, to counter suction of tree that is to the right.
Whistle before ditch even though she was challenging the line well. You wanted to stop dog before you lost site of her in the ditch and wanted her to drive across the ditch with momentum to carry the line. I think this would have been a right back cast, to fight against the scent coming off the poison bird and the tree. You would rather have her a little fat to right at this point.
Whistle to stop. Rats she is giving into that bird/tree suction. I would be giving a verbal with my right angle back cast, would want to get her out of all that suction.
You let her carry the line a while because she did cast out of the suction, Good Dog.
Whistle sit, my guess she saw/winded the blind on the sit.
Right over cast and she picks up the blind.
Wind, I think there is a lot for me to learn about the effects of wind. Right now I'm just trying to make sure I know which way the wind is blowing when I come to the line.
Thanks Swampcollie, nice post.
