poor thing , Now wonder he jumped.
That reminds me of a time I found a halloween mask, and I called my dog over, I was sitting on the floor, around a corner from where, I was holding the mask out and when she walked around the corner she jumped so high! I didn't think it was going to scare her! The mask had been on the ground and she had seen it many times! She forgot about it a second later when she saw me sitting there and same over wagging.
