A dog helped save her owner who was badly injured in a car crash just days before Thanksgiving. John Miles was walking his dog Lucy on Neponset Street in Dorchester, as he does every day, when both of them were hit by a car. John blacked out and doesn’t remember what happened. Lucy, a husky-beagle mix, who was also injured, limped to a nearby dentist’s office and barked until help arrived. She limped back and stayed by John’s side until emergency crews arrived.
