On a summer evening at JFK/UMass Station, police say, a Quincy man robbed a person standing on the platform. The robber’s weapon? The pit bull tugging on his leash.
A few weeks later, Eric Coldwell walked onto the back porch of his Weymouth home and watched as his own 60-pound pit bull terrier, Maizy, tackled his 9-year-old son, Thomas — then slobbered kisses all over him. “If you didn’t know better,” Coldwell said as he watched the scene unfold, “you might have assumed the worst.”
