perfect example and done it many times.
he original post does not say that the handler/dog are asked to step back into the holding blind while the blind is being planted. There are many times when there is already a dog in the holding blind and the judges instruct the handler to just "turn" the dog so he can't see the birdboy planting the blind in the field. Under these circumstances and depending on the handlers decision to do so, it can be benificial to let the dog hold the bird so he doesn't want to turn back around to view the field. It all boils down to knowing your dog and what would work best given the scenario.
