BOSTON -- The City of Fall River is considering a crackdown on dangerous dogs.

A proposed law would force owners to keep pit bulls and rottweilers behind 6-foot fences.

Owners would not be allowed to walk the dogs on city streets.

This proposal comes just weeks after a number of high-profile pit bull attacks.

A Brockton, Mass., man was mauled by a neighbor's pit bull and seriously injured.

The Boston Herald reported that 20,000 people went to Massachusetts hospitals between 2002 and 2004 for dog bites. Most of the bites were not from pit bulls but from the family dog.
