A Tampa woman is speaking out after being mauled by a Rottweiler.Danielle Nelson was going to her friend's house Friday, when a 100-pound Rottweiler broke free from its chain and began charging at her."He's a big dog. He was real heavy, but I had to take him with my arm in his mouth and drag him so I could get inside the house so my friend could close the door on him," said Nelson. "He just kept gripping on my arm hard, so after that I said, 'Don't hit him no more,' and that's when I bit him, and he let me go."Nelson was finally able to crawl to a phone and call 911. The paramedics arrived shortly after.She ended up getting 100 stitches.Besides being a bit shaken up, Nelson is said to be doing well.
