A one-week old puppy has survived after being accidentally flushed down a toilet and trapped in a waste pipe for four hours.

Allison Blair, the mother of four-year-old Daniel, has described how her son tried to wash his pet in the lavatory after he became muddy in the garden.

A plumber was called to the house in west London and rescued the pup with the help of his underground camera.
