From WBKB TV, Alpena, Michigan:
A little over a week ago a city mail carrier was out on her route when she was attacked by a pitbull and sent to the hospital for surgery on her hand and arm. She has asked that we not say her name to protect her in this situation.
The mail carrier had just dropped off the mail and was leaving the porch of the house when she heard the pitbulls.
