At 3:30 a.m. Pearl Carlson was shaken awake by a forceful pull. King, the family dog, was trying to pull her out of bed.Then she smelled smoke and heard the sound of fire from her parent's room. Pearl's screams awaked her mother， Fern and father, Howard, who had recently been in hospital for lung disease. Helping Howard to a first-floor window, Fern told him to climb out, then ran to her daughter.
Still inside, King appeared at Pearl's window, making squeaking (短促尖叫) sounds. When running toward Pearl's bedroom, Fern realized her husband hadn't yet escaped. She made her way back through the smoke and flames, following King's sound to where Howard lay semiconscious (半昏迷) on the floor. Fern helped him get outside. King came out only after both were safe.
As day dawned, the Carlsons saw that King's paws were badly burned, and his entire body was burned too. His chain collar had gotten so hot that it burned his throat, making it impossible for him to bark (叫) normally. Only after the seven-year-old dog refused food did they find pieces of wood in his mouth and realize that King, who slept outside, had bitten through a wood door to warn his family.
