A German dog in Alaska has been given a hero's award for saving his owner's house from
a fire.Buddy guided a team of firefighters through winding roads to the house in an isolated
(偏远的) area.
That day,his owner Ben Heinrichs was working on his truck inside his garage when a spark
ignited some fuel and caught fire.
Ben managed to run outside,closed the door to stop the fire from spreading and rolled in
the snow to put out the flames on his clothes.But he suddenly remembered the dog was still
in the workshop and ran back to fetch him.While Buddy escaped uninjured,his owner suffered
burns to his face and seconddegree burns to his left hand.
The dog ran off after his master said he needed help.On the road he came across the
Alaskan firemen who had been called about the fire.But they had got lost and were about to
turn down the wrong road.When they caught sight of Buddy who made eye contact with
them and raced ahead down the right road,the firemen immediately followed him and he
often turned round to make sure they were behindhim.The dog's quick reaction saved the
family.

his family," said Officer Holloway at a ceremony to honor the dog.Buddy,whose good deed
was shown on a police car's video,was given a smart dog bowl as a reward,and a big bone.
Ben said that he knew Buddy was clever and added that Buddy was brave too,having
