    Dogs may help save the day in the Philippines, as they use their noses to smell out survivors buried by

Friday's mudslide (泥石流). The team of dogs arrived in the Philippines from Spain, and this Tuesday they

were just beginning their work. Search officials told CNN they hoped the recent rain would wash away the

smell of rescue teams so the dogs could do their job more accurately. The dogs were brought in after sound

equipment found sounds coming from deep inside the ruins, at a place where a school stood before the

mudslide covered it. The sounds could mean people are still alive under all the mud or it could just be the earth

resettling.

    On Monday, rescue workers worked at the school site until three in the morning, trying to locate survivors,

and they will begin digging again as soon as the dogs think they find someone. Human teams from the US,

Malaysia, and Australia are all trying to help, too. But so far they have yet to locate any survivors. Rescue

workers told CNN that an earlier report that 50 survivors had been found was false.

     How did all that mud bury the village in the first place? On Friday, 2,400-foot Mt Kanabag turned into a

mudslide after two weeks of constant rain weakened it. The mountain crumbled and the mud fell onto the

village Guinsaugon, burying the 1,800 people who lived there. Out of the 300 houses in the village, only 3

were not covered by the mud. The village is on a southern Philippine Island called Levte. Rescue efforts have

been difficult because the village takes six hours to reach from the nearest airport. Hopefully, the dogs can

help their human friends find survivors.
