Ashley Greene's dog died when her apartment went up in flames on Friday.
The Twilight Saga actress' home in a Los Angeles apartment block caught fire with her two dogs inside and while firefighters were able to rescue one of her fox terriers, the other one didn't make it, according to People magazine.
The 26-year-old actress' representative said the cause of the fire is as yet "undetermined".
Los Angeles Fire Department Inspector Johnson told RadarOnline: "We made an aggressive fire attack. Our team saw smoke and fire coming from the third floor.
"We have reports of two patrons that were burned, so they were treated by the paramedics and sent to the hospital."
