     After a disabled woman's cat started a house fire, her specially trained dog came to the rescue and then died when trying to help the cat still in the house, Jamie Hanson said the 13-year-old dog named Jesse,

brought the phone so she could call 911 and also brought her artificial leg.

     "She got me outside and then she heard the cat upstairs and went up there to get the cat out but she

wouldn't come back to me," Hanson, 49, said at a news conference at Aurora Sheboygan Memorial

Medical Center where she was being treated for her injuries.

     "She received third-degree burns on an arm in the fire at her home," the Sheboygan County Sheriff's

Department said, adding that both pets died in the fire.

     Hanson, who lost a leg in a car accident three years ago, said she was on the couch watching television when the cat ran over the back of the couch.

     "And he jumped onto a table that had a candle on it and tipped it over and finally set the artificial plants on fire," she said.

     Hanson said she fell off the couch and was unable to get her artificial leg from the table. "So my dog got my leg for me and went to get the phone and brought it to me, so I could call 911."

     She said she tried to put the prosthetic leg on, but it was too hot, and the dog, a German shepherd,

came to her aid again before going back inside for the cat.

     When rescuers arrived, the house was fully engulfed in flames, the Sheriff's Department said. Hanson

was in the doorway and was assisted by a deputy (警官).
