Fire did heavy damage Sunday night to a one-story building that housed three businesses at 407-409 Old Oxford Road.
The building, which housed D’s Tobacco and Grocery, Hernandez Used Tires and an auto-repair business that had no name posted, was burning when the first trucks arrived shortly after 8:30 p.m., Deputy Chief Chris Iannuzzi said.
Tire and flammable liquids in the building caused an unusually intense blaze that took firefighters an hour to get under control.
It grew larger again, however, as it traveled unseen between roof sections of the building, Iannuzzi said.
A pit bull guard dog in the tire store died in the heavy smoke and flames, firefighters said, but they were able to save several vehicle, including an antique car valued at $80,000, Iannuzzi reported.
Fire apparatus remained on the scene until about 4 a.m.
