Our adopted lamb used to do this as well, though we didn't have a dog. He loved playing chasey with us in the field, bouncing around, all pretty normal sheep behaviour.
Yes, I do think its worth examining the work of major rap artists, like Kanye and Jay-Z - and for that matter, the work of Missy Elliott and Queen Latifah. A lot of white people dismiss rap and hip hop as 'gangster crap' and sure, some of it is...but you can say the same about pop music, hipster folk blah blah etc. If you don't understand rap, try using http://rapgenius.com/ because it will give you a great deal of insight into what songs are about - even some that you think you know. There are layers within some apparently simple phrases which may not be apparent at first glance. (For the record, Im a white woman in her mid-40s. Open your minds, people.)
I can't blame her for being frightened - and lets not forget she is shielding her child. These are v.large animals, not a domesticated species, and they are very strong. I visited a zoo a few years ago, which included a close up tour of the giraffes. As one of the background stories they told us that one of the giraffes had 'accidentally' picked up and swung a female zookeeper by her ponytail (mistaken for food they think). This was not a small woman.
