Multiple fire crews responded to a 2 alarm row home fire around 8 p.m. Saturday night along the 1300 block of 13th street in Harrisburg.
Officials say the fire started in the back of one of the row homes on the third floor and spread quickly to two adjoining homes. The fire was difficult for crews to extinguish but were able to put the fire out 2 hours later.
The families inside the homes were able to get out safely but one family does believe their family dog was left inside.
Crews are still searching for the dog, no word yet if the dog has been found.
