No one was injured and a family pet was saved Thursday after a home off Canton Highway erupted in flames.

Forsyth County Fire Capt. Jason Shivers said the blaze at 2310 Fair Oaks Court is under investigation, but does not seem suspicious.

It appears the source of the flames was somewhere in the upper central part of the house, Shivers said.

The home's main floor and foyer area, as well as the upstairs bedrooms, received heavy fire damage. He said furnishings in the downstairs bedrooms will be salvageable and the garage was untouched.

Ann Santos lives in the home, which is in the Hunter's Walk subdivision, with her husband and three children ages 2 through 10.

Brow furrowed and phone in hand, Santos walked around her house surveying the damage Thursday afternoon.

"I have no idea how this happened," she said.

Her 3-year-old pit bull mix, Chulo, was inside the house when the fire started.

Firefighters rescued the dog and treated him using a pet oxygen mask. A passer-by who saw the fire later took the dog to a nearby veterinary clinic.

Santos said she didn't know the woman before the incident.

"She just called to tell me he's there, but they're going to keep him overnight," she said. 

The fire was reported about 2 p.m., with heavy flames and smoke billowing from the front of the home when firefighters arrived.

They had the blaze under control within 20 minutes and had cleared the scene by about 5:15 p.m.

"Firefighters initiated a very aggressive interior attack in a very dangerous situation," Shivers said. "Those efforts proved successful through the use of multiple fire units delivering numerous firefighters to the scene."

He said they used a compressed air foam system, which uses a mixture of water, air and foam to suppress flames, cool the structure and prevent it restarting.

Four fire engines, one ladder truck, one ambulance and a variety of command staff and fire investigators responded to the incident. In all, 25 personnel were involved, Shivers said.
