My boss did the board and train with one of his golden retrievers. She returned a completely different dog, in a bad way. She is now DA through fences and on leash, freaks out when given a bath or when her feet are touched ( she loved this before, now she panics, yelps, snaps, etc). She also barks at anything that makes noise, which she did not do before.
Granted she's a golden, but i would not recommend them after seeing the results she's had.
