Three days after a seven-year-old boy was killed by pit bulls in Lowell, city councilors unanimously voted to investigate prevention measures to restrict this breed of dog. But animal rights advocates argue the breed is not the problem, it’s how owners treat them.
 
Lowell City Councilor Rodney Elliott — an advocate for restrictions on the breed — and Michael Keiley, director of adoption centers and programs for the Massachusetts Society for the Prevention of Cruelty to Animals joined Jim Braude to debate.
