UPDATE 8/2/12: S.2192 was signed by the governor today and will become effective in 90 days. Congratulations to Massachusetts!
Massachusetts S.2192 is a bill that overhauls Massachusetts state animal laws. It includes several clauses that would prohibit municipalities in MA from passing breed-specific laws. S.2192 is on track for third reading in the House.
The most recent amendment to S.2192, which is House document 4266, contains two clauses that would prohibit BSL:
Section 157. (a) Any person may file a complaint in writing to the hearing authority complaining that a dog owned or kept in the city or town is a nuisance dog or is a dangerous dog; provided, however, that no dog shall be deemed dangerous: […] (ii) based upon the breed of such dog; […]
No city or town shall regulate dogs in a manner that is specific to breed.

We do not not know whether the bill would be retroactive (e.g. would force MA municipalities that currently have BSL to repeal those laws).

Stop BSL 
Can someone provide the person(s) names who started this Bill? I would love to contact them and see how they went about doing it as Rhode Island needs this law too!
Darlene, try contacting the MSPCA (http://www.mspca.org/).
Senator Patricia Jehlen of Sommerville…I would like to hug her!
