UPDATE, 2 p.m. Found at a gas station in Newton.
Among the occupants of the house at 72 Perthshire Rd. in Brighton that went up in flames last night was Layla the dog, who ran away and hasn't been seen since.
She's described as a shy, four-year-old pit bull. If you spot her, don't try to chase her, but instead call the number at the link.
