Over the years I've watched this woman reduce people to tears (myself included) in a training ring. If they've got a dog with the potential to beat her in an Obedience ring, she'll grind them down, so they lose all confidence to go on & trial their dog and they eventually leave club, never to be heard of again. Unfortunately, she is just not able to separate trophy hunter from trainer when she gets someone good in the ring to train.
The best mentor & trainer I ever had while I was bringing Zena through, was a club member who was also an instructor, competitor & judge in the discipline. Unfortunately he had a fatal heart attack right in front of us at a dog trial. Gone too soon at 46. Zena just loved him. There were very few people she would let willingly touch her. This chap was one of them & she got her best scores ever every time we stepped into a ring with him when he was judging.
