Robert Godwin holds his dog Penny, who escaped from a fire at their house at 4816 Ashland Drive Tuesday afternoon about 2 p.m. No one except Penny was home at the time, and no one was injured, but the single-story house was heavily damaged. Four fire trucks, two ambulances and about 18 firefighters responded to the emergency call in four minutes, said Tampa Fire Rescue Capt. Bill Wade. The blaze probably started on the west side of the house, Capt. Gary Howcroft said, but the cause could not be determined until firefighters finished their investigation. Godwin said his pet was locked in the house but somehow managed to escape.
