I have a story ..Our daughter Dog Sat for folks while she was in college. One family owned a very needy Border Collie named Jamie..Well Jamie is terrified of thunder, fire workes, backfires any thing that goes bang..Chelsey was well aware of the problem and made all preperations for the problem..However one day she was teaching at summer school and a midday storm blew in..She raced home and no Jamie.. he it seems had crashed through the window and screen..of the second story bed room where he had been left for safety. You see if there is a bang Jamie will run away from the sound...Well Chelsey was in a panic.. she was scared to death for Jamie and for facing the family who owned him.. To make matters worse the family came home early and no Jamie...The child in the family just sat down on the floor and screamed...Chelsey was in a fit...They set out on a search of the neighborhood in the rain and thunder.. Well to end on a high note there was Jaime cowering in the corner of a garage the last house on the street.. He survived the fall not even a limp and Chelsey retired from dog sitting.. Jamie is still afraid of loud noises....KGH
