Primary selection is a very difficult task. If you don't train on it - and very few of us do - then don't expect success if you try it at a trial.Can someone tell me: if you think you could get your dog off that flyer and picked up one of the other birds first, would you have done that? Would there have been an advantage in this test to have a dog who could be convinced to come off the flyer for another bird?
Just asking. Have no clue.
