Ever been attacked by a dog?

once when I was staying over someones home, he had a couple dogs including a Pitbull. when I passed through the dogs area he did not react. then one time when I entered when he was playing his owner the dog became agitated and started jumping all over me. then like he thought he was in a bar fight his paws shot out and he SHOVED me pretty hard. then he bared his man killer fangs at me and as I was just standing there he growled. it was like some freak in a horror movie. luckily his owner intervened and I left soon after. ever since that day I've seen pitbulls in a whole new light and not in a good way.
