sheep story of thinking

how a sheep decided to jump over a ditch
I once saw a sheep that was at the wrong side of a fence. I stopped and thought how I could help it get to the other side. While I was thinking, the sheep seemed to realize I was a threat and suddenly panicked and jumped over the ditch all hooves in the air spread in four directions thus getting at the other side of the fence. I was surprised. It seemed this sheep thought before it panicked, and then decided to act upon it. The thinking process took quite some time.
Was this sheep thinking? Did it decide I was a threat? Did it then decide she should act upon her fear? This all seemed to be the case.
