Barking at a snowman

My pup went out to pee the other night and went to a side of the house she hasn't gone to much because of deep snow. She ran out of my line of sight and started barking furiously. As I rounded the corner, I saw what she was yapping at. It was a 5 foot high snowman. After a minute of the snowman not moving, she lost interest and focused on her business at hand.

My pup chooses barking when she comes across something that scares her. Being so small she is so much out of her element. She barks, but doesn't sound very frightening, more annoying.

I wonder what I look like when I become frightened?
