Around 4:30 p.m. Sunday on the 3100 block of Memphis Street, Andrea Bulat's dog started barking.
"Her dog, Che... the dog's really protective of her," neighbor Anthony Daly told Action News. "If you go past her house it's 'Bark, bark, bark, bark!' and that kind of stuff."
But neighbors say it was highly unusual for Che to be barking that early in the morning. That's what woke them up.
"When I looked out the window you could see the flames," said Daly. "The whole first floor was engulfed."
When firefighters arrived, they found the dog on top of Bulat, who was unconscious.
"The dog stayed on her chest the whole time, which prevented her from being burned totally," said another neighbor, Adele Butler.
Bulat was rushed to Temple University Hospital, where she is listed in critical condition with burns over 50 percent of her body.
Firefighters used oxygen to resuscitate Che. The dog is at an animal hospital in Langhorne, Pa. being treated for smoke inhalation.
Neighbors are calling Che a hero.
"I think it's a beautiful thing, because I've always heard stories of where animals would help save their owners," said neighbor Thomas Leszcewicz. "I've never lived one. Now I've lived one. I've seen it with my own eyes. That's a beautiful thing you know."
"I think because of the dog being there, that really saved her," said Butler. "If the dog wasn't there, she'd probably be dead."
A spokeswoman for the Red Paw Relief Team said Che, who is at least 10 years old, is an 80-pound mixed Chow and Golden Retriever.
They say it's uncertain if the animal will survive because of the degree of smoke inhalation and its age.
The cause of the fire is under investigation.
