A reporter once flashed a shot at my dog as she was approaching a jump in the ring in utility, she had not flunked once in her 38 times in the ring career to that point, she didn't startle easy at all but the flash distracted her as she reached the jump, she stopped and stood there staring at him...and we flunked. Flash is not good for horse shows either for the same reason. You can get lynched at a show for less LOL.
